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 ...
Model analysis of bucket wheel excavator SchRs 630 strength
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The possibilities of testing real constructions are often limited, especially in case of large constructions. The idea of model testing is to create a sub-scaled model in order to anticipate the behavior of the real ...
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, ...
Probability distribution on cleavage fracture in function of Jc for reactor ferritic steel in transition temperature region
(Engineering Failure Analysis, 2021)
This paper presents the results and methods used for determining of probability of cleavage fracture toughness of ferritic reactor steel in transition temperature area. The steel tested in this study is steel know as ...
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 ...
