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 ...
Crack path direction in plane-strain fracture toughness assessment tests of quasi-brittle PLA polymer and ductile PLA-X composite
(Elsevier BV, 2022)
Plane-strain fracture toughness is one of the main parameters in linear elastic fracture mechanics and its purpose is to show the material capability to withstand load while having a defect. Main validity aspect for such ...
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 ...
Side-groove effect on fracture mechanical fatigue testing of PLA material
(Elsevier BV, 2022)
PLA polymer is probably the most used thermoplastic material in FDM technology nowadays. Besides prototyping purposes, FDM materials are also considered for functional application use, thanks to the fast fabrication of ...
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 ...
Solution for consolidation and retrofitting a historical steel bridge
(Procedia Structural Integrity, 2022)
Sustainable development is a fundamental goal of the European Union and seeks to meet the needs of the present, without compromising the future. The rehabilitation of historic steel constructions and old steel bridges in ...
Analysis of fatigue behaviour of a bridge welded structure
(Procedia Structural Integrity, 2022)
Results of extensive experiments involving the fatigue behaviour of welded structures which are a part of the “Gazela” bridge in Belgrade, Serbia, are presented in this paper. After non-destructive testing of these structures, ...
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 ...
Additively manufactured tensile ring-shaped specimens for pipeline material fracture examination - influence of geometry
(Elsevier, 2022)
In order to define a procedure for integrity assessment of pipelines and determining the fracture mechanics parameters, a new type of specimen with a sharp notch, Pipe Ring Notched Tension (PRNT) specimen, is tested. The ...
