Influence of mechanical properties of welded joint regions on pipeline structural integrity
(The 27th International Conference on Fracture and Structural Integrity, 2023)
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 ...
Numerical simulation of crack growth in welded joints in the presence of multiple defects
(The 27th International Conference on Fracture and Structural Integrity, 2023)
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 ...
Comparison of two recent approaches to DTB characterization of ferritic steels
(Elsevier B.V., 2023)
The large scatter of the experimental fracture toughness data, characteristic of all ferritic steels in the ductile-to-brittle transition temperature region, imposed the need to include statistical methods for data processing. ...
A METHOD FOR FRACTURE PROBABILITY ASSESSMENT IN FUNCTION OF J-INTEGRAL IN TRANSITION TEMPERATURE REGIME OF FERRITIC STEEL
(University of Belgrade - Faculty of Mechanical Engineering, 2023)
In this paper is presented the 1-point method for material behaviour prediction, in terms of fracture toughness, of the ferritic steel EN 1.6310 in the transition temperature regime (-60°C and -90°C). Experiments were ...
UPGRADED TWO-STEP-SCALING APPROACH TO THE DTB CHARACTERIZATION OF FERRITIC STEELS
(9th International Congress of the Serbian Society of Mechanics (ICSSM), July 5-7, 2023, Vrnjačka Banja, Serbia, 2023)
The fracture toughness of ferritic steels in the DTB (ductile-to-brittle) transition temperature
region is a stochastic extrinsic property known for pronounced experimental data scatter that
necessitates statistical ...
Editorial of the 2nd IRAS conference
(Procedia Structural Integrity, 2023)
The Second International Symposium on Risk Analysis and Safety of Complex Structures and Components (IRAS 2023) took place between 2-4 April 2023 at the Faculty of Mechanical Engineering of the University of Belgrade. The ...
Mechanical characteristics of compressive specimens obtained by SLS technology
(2nd International Symposium on Risk Analysis and Safety of Complex Structures and Components (IRAS 2023), 2023)
The purpose of this research is to investigate the mechanical properties of Additive Manufacturing(AM)parts. The 3D printer used in this study is Fuse 1 (FormLabs, Summerville, MA), which utilizes theSLS(Selective Laser ...
Investigation of the tensile strength of polymer materials obtained through 3D printing technologies
(Innovation Center of Faculty of Mechanical Engineering, Belgrade, Serbia, 2023)
The subject of this paper is the experimental testing of 3D-printed polymer materials and their tensile strength. The focus was on testing polymer materials that are easily accessible, cost-effective, and do not have ...
Biomimetics Design of Tooth Root Zone at Cylindrical Gears Profile
(MDPI AG, Basel, Switzerland, 2023)
During the last few decades, the requirements for modern machine elements in terms of size reduction, increasing the energy efficiency, and a higher load capacity of standard and non-standard gears have been very prevalent ...
Crack tip fields effects on crack propagation through the heat affected zone in an overmatched welded joint
(2023)
The mismatching constraint effect on crack propagation through the heat-affected zone (HAZ) in a welded joint is presented in this paper. It is shown that due to this effect, the fracture behavior of an overmatched welded ...
