Numerical simulation of fatigue crack growth in AA6156 T6 panels
(Elsevier B.V., 2021)
Fatigue crack growth in a panel with 4 stringers and 3-clips, made of AA6156 T6, was modelled numerically using xFEM. The central crack of the length a=17 mm was propagated in the total of 91 steps (in each step crack ...
Fracture behavior of reactor steel 20MnMoNi 55 in the transition temperature region
(Elsevier B.V., 2021)
The fracture represents the final phase of crack propagation, and the causes of their occurrence or partial crack propagation in the real constructions made of ferritic steels can be different. Along with cracks, influences ...
Reliability-based structural analysis of a bucket wheel excavator's load-bearing steel structure
(Procedia Structural Integrity, 2022)
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, ...
Influence of printing parameters on the eligibility of plane-strain fracture toughness results for PLA polymer
(Elsevier B.V., 2022)
The majority of manufacturers of polymer filaments for FDM technology rely their datasheets only on tensile tests, so their documentation usually lacks any data concerning fracture mechanics parameters. Having in mind the ...
Pitting and uniform corrosion effects on ultimate strength of a bulk carrier
(Procedia Structural Integrity, 2023)
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 ...
Residual life estimation of damaged structures exposed to high pressures and temperatures
(ELSEVIER, 2023)
This paper deals with the damage growth in High-Pressure Turbine (HPT) cooling holes of the case assembly made of Inconel 718. Several marks (cuts) were made on cooling holes into parent material during the service due to ...
History of ductile-to-brittle transition problem of ferritic steels
(Procedia Structural Integrity, 2022)
This paper presents a review of different approaches through history concerning DTB transition phenomenon of ferritic steels and their characterization using FM concept, from the earliest studies based on LEFM to the ...
Methodology for Analysing Risk Factor on Surface Top Hammer Drill Rig
(Elsevier, 2023)
Two-level risk mapping and assessment methodology was proposed with several criteria for risk prioritization (frequency of occurrence, downtime, level of danger, type of stoppage, cause of downtime, risk number). In a ...
Numerical simulation of fatigue crack paths in orthopedic plates
(Elsevier B.V., 2021)
This study is aimed to explain the behaviour of different orthopedic plate designs, under uniaxial bending, with cracks initiated in the stress concentration areas. Extended finite element method (XFEM) in ANSYS software ...
Predicting fatigue crack growth in complex geometries using numerical methods
(Procedia Structural Integrity, 2023)
Fatigue cracks growth in three different wing spar geometries is simulated using xFEM, as the most suitable numerical method for this purpose. The goal of this analysis was to find out how crack paths affect number of ...
