AB  - Standard structural assessments of ship hulls include the evaluation of the elastic structural response. Elastic analysis neglects extreme and unpredicted loadings, which can produce catastrophic outcomes, such as the loss of the ship’s ultimate strength. Moreover, hull elements are considered unaffected by age-related degradation. Therefore, this study models and quantifies the effect of corrosion-induced structural degradation on the ultimate strength of a high-tensile-steel (HTS) cargo ship using progressive collapse and nonlinear finite element methods. Uniform and pitting corrosion are modeled through selected scenarios, which hull elements might encounter during exploitation, producing a total of 148 calculation models. The findings show that corrosion-induced degradation can significantly decrease the ultimate strength of the hull (up to 30% for the most severe scenarios assessed). Furthermore, ultimate strength decreases almost proportionally to the amount of wastage considered. It was found that stiffener corrosion has a significant effect on the total ultimate strength. This study’s aim is to emphasize the vast importance of including ultimate strength along with ageing effects in industry-standard structural assessments of large HTS ship structures, designed to last for several decades whilst exposed to excessive and unpredicted bending moments.

AB  - Failure analysis of welded joint with multiple defects was performed taking into account the effect of all defects, not just a dominant one. Four cases of multiple defects in welded joint under the uniaxial tensile loading were investigated using extended Finite Element Method. Two-dimensional Finite Element Models were made according to the tensile specimens with initial crack located in a critical area of welded joint. For each multiple defects case, numerical simulation was performed with three initial crack depth. Engineering Critical Analysis was made using Failure Assessment Diagrams for each defect that was determined as critical for its welded joint case. Numerical simulation showed that the geometry of the most prominent one from a point of view of structural integrity. It was concluded that the vertical misalignment in combination with a secondary defect, had the most adverse effect which can lead to failure of welded structure.

AB  - Within the theory of thermo-elasticity, the temperature field of thin plates 
is commonly defined via two parameters: temperature in the mid-plane and 
linear temperature gradient normal to the mid-plane. First, the paper 
analytically proves the justification of that assumption in machine 
structures. Then, in an analytical closed form, applying the integral 
transformation method, the thin plate deflection caused by a constant 
temperature gradient is defined. It is shown that, in that case, the plate 
deflection does not depend on its thickness but only on the plate 
dimensions in the mid-plane. Analytically defined values are compared to 
corresponding values obtained by applying the thin plate finite element, 
where the temperature field is described using the two mentioned 
parameters. This finite element is defined and programmed within the 
Komips program package. The influence of the temperature gradient on 
the behavior of constructions mostly depends on the type of material. That 
is why the behavior of some structural elements made of brass, steel, and 
concrete is analyzed in this paper.

AB  - Simulation of crack initiation and propagation which occurred during the tensile
testing of real welded joint specimens made of low-alloyed low-carbon structural
steels is presented in this paper. Welded joints in questions were made with a
number of different defect combinations [1-3], such as excess weld metal, undercuts,
vertical misalignment and incomplete root penetration. Tensile tests were performed
on specimens divided into four groups according to their defect combinations, along
with numerical simulations using finite element method [4-6]. Once numerical models
which were valid in terms of stress and strain distribution were obtained, cracks were
introduced in the most critical locations, which corresponded to the real specimen
locations were failure of specimens initiated. The goal was to observe the behaviour
of models in the presence of these cracks, since in the case of experimental
specimens, fracture behaviour was often unconventional, due to complex geometry
which caused them to deform in unexpected manner. This geometry was influenced
by the presence of multiple different defects in the welded joint, and in some cases
even resulted in stress states that were not uniaxial, as is usually the case with
experiments and simulations like the one presented here

AB  - This paper is based on extensive research about the influence of multiple different welded joint defects on the integrity of welded structures. In this particular case, the focus was on the heat affected zone and its different sub regions - up to this point, it was observed as a whole, with homogeneous mechanical properties along its cross-section. Due to the need to describe its behaviour in more detail, it was concluded that metallographic characterisation of the heat affected zone is necessary. Metallographic tests have provided a detailed insight into the micro-structures with the heat affected zone, which would be difficult to predict in this case, due to specific conditions, i.e., a welding technology which was adopted with the purpose of deliberately causing a number of defects in the welded joint. This would result in a more realistic distribution of mechanical properties along the heat affected zone, which in turn would provide more accurate input data for numerical simulations, since the use of finite element method will be the next step in this research.

AB  - Risk analysis of containers in a coal drying facility was performed using the Failure Modes and Effects Analysis (FMEA) method in combination with the risk matrix. The selected exploitation period analysed for all vessels was 5 years, since there is a lot of data about the maintenance performed during this period, including results of material testing performed by an accredited laboratory. Based on all issues detected by testing, risk probabilities (with corresponding levels of severity) of various defects were calculated, and potential expected repair costs determined. These probabilities were then used as input for the risk matrix which indicated the most critical types of defects, both in terms of occurring probability and the severity of their occurrence. It was concluded that through-thickness cracks were the most dangerous defect in this case. Furthermore, high probabilities of most defects considered, implied that containers will become unreliable and unfit for continued exploitation in the near future. Suggested means of preventing failures include a more thorough periodic maintenance and control of these vessels, until it is possible to fully replace them with new equipment.

AB  - The research represents the ongoing investigation of the welded joints behavior made
of low-carbon low-alloyed steel in the presence of different multiple defects. Following the initial
experimental and numerical analyses performed on low-grade steel, a set of experiments were
performed with specimens made of steel EN 1.0044 (commercial designation S275JR), along with
development of new numerical models. Four combinations were made, including defects like
undercuts, excess weld metal, misalignment, weld face sagging and incomplete root penetration,
considering that these defects are often encountered in practice, and can appear simultaneously. The finite element method (FEM) was used to simulate the experiments. Tensile properties of the HAZ and weld metal were calculated using strain measurements by the digital image correlation (DIC) method. The finite element method (FEM) results were in good agreement with the experimental ones.

AB  - The paper presents analytical and numerical determina-tion of the equivalent stress and strain of the open section thin-walled ‘’ cantilever beams loaded with torsion. Ana-lytical calculation was used to calculate the equivalent stress and strain values for the model encastred across the entire cross-section at one end, while the other end is free (model 1). The finite element method is applied for the calculation of the same ‘’ cantilever beam model exposed to torsion, and the stress and strain values are obtained by numerical calculation. Numerical simulations have been performed using KOMIPS software. Analytical and numerical results are compared and discussed. In this paper, a numerical model for constrained torsion is also created in ABAQUS® and SolidWorks® software. A cantilever beam with an omega profile is encastred at one end, while at the other end there is a welded plate (model 2). Numerical models are created, and static calculation is done using the finite element method. The zones of stress concentration are identified and presented. Finally, the equivalent stress values of models 1 and 2 are compared. Conclusions obtained by examining this type of structures may be involved in the design process of new similar structures. The findings obtained during the implementation of this work can be directly applied to iden-tify the behaviour of real structures in their working condi-tions.

Influence of mechanical properties of welded joint regions on pipeline structural integrity

AB  - In this paper, a material characterization inverse methodology is used to obtain
structural parameters for all welded joint regions. Furthermore, such are applied for
the more realistic analysis of the pipeline numerical model structural response.
Material characterization methodology included tensile testing of specimen
containing welded joint. During the experiment strain field was continuously
measured using stereo cameras, and results are processed using system based on
Digital Image Correlation. Numerical computational model of test pipe is formed
using the same parameters, as in the experiment (shape of welded joint, boundary
conditions, loads, etc.). To improve numerical model, deformations of all regions of
welded joint (base material, weld metal, and heat affected zone) are imported into
numerical model. Consequently, material properties (Young’s modulus of elasticity,
yield strength, tensile strength) of all three welded joint regions were obtained.
Material properties are then used in analysis of welded joint influence to structural
integrity. Three different numerical computational models are produced. The first
model represents the classical approach in which the welded joint parameters are
not considered. The second model contained welded joints, but with orientational
mechanical properties of base and weld metal, and with heat affected zone having
properties same as base material. The third one included properties of all three
welded joint regions, obtained using inverse methodology. Results showed that there
is no difference between the models during service operations (elastic structural
behaviour). However, within the plastic deformation domain, which for instance,
accounts for hydraulic shocks, the differences are considerable. When orientational
mechanical properties of base and weld material are included, stress concentration
in welded joint is 1.59. When real properties of material are included, stress
concentration is decreased to 1.49, while stress gradient in welded joint area is
smaller than in previous model. Thus, welded joint modelling can vastly influence the
plastic domain structural behaviour of the pipeline structure.

AB  - In general, ship structural integrity assessments consist of prescribed procedures given by the rules of classification societies, and if necessary, direct calculations. Direct calculations mostly include longitudinal strength analyses and buckling calculations for various service loadings and structural members. Resulting stress is compared to the allowable stress, which is also rule-prescribed and acts as a share of the yield stress of the material. This means that the structure is evaluated upon its elastic response. Moreover, ship structural assessments consider as-built scantlings, not diminished by ageing. Generally, extreme or once-in-a-lifetime loadings are neglected. They can include overloading scenarios that lead to the ship structural collapse or the loss of the ship’s carrying capacity, i.e., ultimate strength. Ultimate strength of the ship is represented by the maximum (ultimate) bending moment the structure can withstand. Its evaluation is important to determine the ship’s structural safety level with respect to its collapse. Therefore, this paper delivers the ultimate strength assessment for a typical bulk carrier having 180 m in length. For this purpose, an incremental-iterative progressivecollapse analysis (PCA) is used. In the first stage, ultimate strength of a bulk carrier is determined using as-built scantlings. In the next, ageing effects are considered within PCA by modeling scenarios that include both pitting and uniform corrosion. Pitting corrosion is defined by pitting intensity degree (DOP) and corrosion intensity degree (DOC), whilst the uniform corrosion is defined by thickness reduction. Results show that corrosion effects can significantly diminish the ultimate strength of the ship. This means that, in the design phase, structural assessments cannot be based just on as-built scantlings, but also might include ageing effects, as ships are designed to be reliable on the long-term.

AB  - Traditional approach in construction designing and structural integrity assessment implies
numerical calculations performed on the construction including construction elements that affect
rigidity and strength, without welded joints. That structure is evaluated in elastic response, and the
results are compared to yield strength, as shown in [1]. That approach is good enough for workloads
for most of the constructions. In that scenario, sudden overloading that led to structural collapse is
neglected. In those scenarios, within the plastic deformation domain, the differences in mechanical
properties of welded joint regions have vast influence to structural integrity. Mechanical properties
of welded joint regions are obtained using inverse methodology, that is mentioned in [2]. That
methodology included tensile testing of a specimen containing welded joint. During the experiment
strain field was continuously measured using stereo cameras, and results are processed using system
based on Digital Image Correlation. Numerical computational model of test specimen is formed using
the same parameters, as in the experiment (shape of welded joint, boundary conditions, loads, etc.).
To improve numerical model, deformations of all regions of welded joint (base material, weld metal,
and heat affected zone) are imported into numerical model. Consequently, material properties of all
three welded joint regions were obtained. Material properties are then used in analysis of welded joint
influence to structural integrity of several constructions, such as pipeline, pressure vessel, bucket
wheel excavator computational models. For all those constructions, two computational models are
made, the one without (classical approach) and the other containing welded joints. Results showed
that there is no difference between the two computational models during service operations (elastic
structural behaviour). However, within the plastic deformation domain, the differences between the
models are considerable. As extension of this research, plans are to perform experiments on real
constructions containing welded joints, applying the same inverse methodology. In that way,
considerable influence of mechanical properties of welded joint regions to structural integrity will be
confirmed. Also, dependence coefficient between tensile testing specimen and the real welded joint
regions on the real constructions can be formulated

AB  - There are numeruos examples of failure of responsible parts of steel structures.
When failure occurs, series of procedures are performed in order to obtain the cause of
failure and to repair the damage. However, prevention of failure should be given higher
importance. That means that one can predict reaction of construction in any unexpected
circumstances, having owerall knowledge about construction. Actually, dynamic
reanalysis method and model testing could give comprehensive insight into structural
behavior of construction. Dynamic reanalysis method implies that the stress is not the
only indicator of weak points in structural design. One should know modal shapes and
natural frequencies, and distribution of potential and kinetic energy in the main modes.
In fact, the main mode shapes show how the structure behaves under some possible
load. Reanalysis method is based on distribution (of difference) of kinetic and potential
energy and involves the transformation of the existing models in the new (better) one.
Model testing represents one of the solutions to obtain the whole picture of
construction behavior and includes creation of sub-scaled model in order to anticipate
the behavior of the real construction, regarding the behavior of the model. Model
testing enables to predict the stresses and deformations, and dynamic behaviour of the
real structure regarding the stresses and deformations of the model, and testing on the
model instead of the actual construction results in a great saving of money and time.
Once again, dynamic reanalysis method and model testing give owerall knowledge
about construction.

AB  - Structural analysis of large structures such as bucket wheel excavators (BWE) are generally performed using the finite element analysis and assessed according to the portion of the material's yielding limit. Consequently, a structure is evaluated just by the maximum stress at the specific location. In order to address the whole structural response of the object, this paper introduces a reliability-based structural evaluation presented on a case study of the BWE SchRs 630. Although the BWE reliability has been explored in literature, most of the research was based on data obtained from failure of systems and structure, over the years. Nevertheless, this investigation is dividing the pure structural from the system failure by mapping and analyzing the specific structural zones of the BWE. Finite element method obtained randomized stresses (i.e., D – demand of the structure) in a structure are categorized as independent variables and modeled using probability density function. The same is performed in case of the criterion – yield strength of the structure's material (i.e., C – capacity of the structure). Furthermore, yield strength distribution itself is evaluated according to the industry's practice meaning that mean value of the yield stress is to be reduced when used as a criterion for the stress assessments. Therefore, a margin function is analyzed according to the equation: M = C – D. Consequently, the structure is assessed as a whole through the introduction of the reliability index based on stresses. Such evaluation could enable comparison between the corresponding and similar structures in terms their structural response in more holistic manner.
