Welded joint geometry effect on fatigue crack growth resistance in different metallic materials
(Elsevier Sci Ltd, Oxford, 2021)
Fatigue crack growth through different welded joint regions was investigated, in terms of welded joint geometry and fatigue crack position. In the first phase of investigation, numerical simulation of crack growth in a ...
Structural integrity and life assessment of rotating equipment
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Failures of rotating equipment often cause severe consequences, so it is necessary to study their integrity and life as detailed as possible, especially when crack is detected. In the case studied here, hydro power plant ...
Procena integriteta rotacione opreme primenom parametara mehanike loma / Estimation of rotary equipment integrity using fracture mechanics parameters
(Univerzitet u Beogradu, Mašinski fakultet, 2020)
Integritet konstrukcija kao naučna i inženjerska disciplina kao deo mehanike loma obuhvata analizu stanja i dijagnostiku ponašanja i otkaza, procenu veka i revitalizaciju konstrukcija, kao što je poznato od ranije. Primenom ...
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 ...
Fatigue crack growth in locking compression plates
(Elsevier Sci Ltd, Oxford, 2022)
Fatigue crack growth in orthopaedic locking compression plates (LCP), under four-point bending, has been simulated by the extended finite element method (xFEM) to assess LCP optimal geometry in respect to remaining life. ...
Some problems of xFEM modelling of surface crack growth in a turbine shaft
(Procedia Structural Integrity 23 European Conference on Fracture, 2022)
One of the major problems in numerical simulation of fatigue loading represents the generation of a finite element mesh, since the model with crack cannot use combinations of different types of mesh elements (such as HEX ...
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 ...
Numerical Simulation of Fatigue Crack Growth in Different Welded Joint Zones
(Springer Science and Business Media Deutschland GmbH, 2022)
This paper involves the numerical analysis of fatigue behaviour of welded joints made of steel SA-387 Gr. 91, with special attention devoted to its regions, which have very different mechanical and fatigue properties. ...
