Stringer effect on fatigue crack propagation in A2024-T351 aluminum alloy welded joint
(Elsevier Sci Ltd, Oxford, 2017)
This paper describes fatigue crack growth in a friction stir welded T joints made of aluminum alloy A2024-T351 under three point bending loads. For this purpose, three dimensional homogeneous isotropic model is used to ...
Fatigue crack paths in light aircraft wing spars
(Elsevier Sci Ltd, Oxford, 2019)
Different cracks paths in three different wing spar designs are analysed (differential, integral and optimized integral) to explore how those cracks paths affect fatigue life estimation. First, numerical analysis was carried ...
Stress Corrosion Crack Growth Simulation by the Finite Element Method
(Springer Science and Business Media Deutschland GmbH, 2022)
Stress corrosion crack growth in mild steel was investigated by using the finite element simulation method. A model simulating crack growth considered an edge crack located on the metal surface, under tensile remote stress ...
Determination of optimum wing spar cross section for maximum fatigue life
(Elsevier Sci Ltd, Oxford, 2019)
Shape optimisation is a nowadays-standard requirement in the design of lightweight structural components. In this paper, optimisation of I-beam cross-section of integral aluminium 2024-T3 wing spar is presented, taking the ...
Stress intensity factors numerical calculations for two penny shaped cracks in the elastic solid
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In the face of enormous costs of developing new aircraft, high fuel prices, increasingly demanding environmental standards, harsh economic race and the fight against competing manufacturers, today's aviation is adapting ...
Application of Numerical Methods in Design and Analysis of Orthopedic Implant Integrity
(Springer International Publishing Ag, Cham, 2019)
In this paper a numerical analysis of hip implant model and hip implant model with a crack in a biomaterial is presented. Hip implants still exhibit problem of premature failure, promoting their integrity and life at the ...
Numerical simulation of fatigue crack propagation in friction stir welded joint made of Al 2024-T351 alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded T joints has been simulated numerically. Crack propagation in stiffened part of the structure between two ...
Failure analysis of welded joint with multiple defects by extended Finite Element Method and Engineering Critical Analysis
(Elsevier, 2024)
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 ...
