The failure analysis of the star-separator of an aircraft cannon
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This paper analyzes the causes of fracture of the double pipe aerial cannon stellate starseparator, which occurred during the fighting plane mission. The linear finite element method (FEM) is used to determine the stresses ...
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 ...
Fatigue life assessment of orthopedic plates made of Ti6Al4V
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
This study is aimed to analyse fatigue life of orthopedic plates due to cracks initiated in the stress concentration areas. Material used for this analysis was typical orthopedic alloy, Ti-6Al-4V, strong but not very ...
A scaling approach to size effect modeling of J(c) CDF for 20MnMoNi55 reactor steel in transition temperature region
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
Ever since the 1980s there is a sustained interest in the size effect, as one of the most pronounced consequences of fracture mechanics. In the present study, the investigation of the size effect is focused on estimation ...
Effect of material heterogeneity and testing temperature on fatigue behaviour of Cr-Mo steel welded joints
(Elsevier Ltd, 2022)
Successful application of Cr-Mo steel depends crucially on behaviour of all zones in welded joints, i.e. base metal (BM), heat-affected-zone (HAZ) and weld metal (WM), both at room and working temperature. Different amplitude ...
Evaluation of true stress-strain diagrams for welded joints by application of Digital Image Correlation
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Digital Image Correlation (DIC) is applied to evaluate stress-strain diagrams for welded joints in two different ways. The first one is based on the measures strains along the welded joint, including all 3 zones of interest, ...
Corrigendum to “A scaling approach to size effect modeling of Jc CDF for 20MnMoNi55 reactor steel in transition temperature region”
(Engineering Failure Analysis, 2022)
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 ...
Experimental and numerical evaluation of fracture characteristics of composite material used in the aircraft engine cover manufacturing
(Pergamon-Elsevier Science Ltd, Oxford, 2022)
The aircraft industry is a leading industry in terms of the implementation of new materials and technologies. In the development of a light aircraft several different materials were considered for the engine cover design ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
