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 ...
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 ...
Corrosion induced failure of the ductile iron pipes at micro- and nano-levels
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Corrosion induced failure of buried ferrous pipelines causes significant economic losses to the world. Many of the existing buried water pipelines are made of ductile iron in most of the developed countries. Literature ...
Failure analysis of a special vehicle engine connecting rod
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
This paper presents failure analysis of the connecting rod used in a 12-cylinder diesel engine set on a special vehicle. The fracture of the connecting rod occurred during the engine test in laboratory conditions. Chemical ...
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, ...
Failure analysis and reconstruction design of the slewing platform mantle of the bucket wheel excavator O&K SchRs 630
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The slewing platform is the fundamental part of the bucket wheel excavator (BWE) structure. The occurrence and propagation of cracks in the zones of the slewing platform mantle holes, may probably lead to BWE collapse. The ...
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 excavator Integrity assessment of the bucket wheel boom tie-rod welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The bucket wheel boom tie-rods are vital structural parts of the bucket wheel excavators (BWE) Their failures inevitably cause BWE collapse and are followed among other things by a substantial financial loss (millions of ...
Testing of the condition and performance of coupling links from screw couplings of train
(Elsevier, 2024)
This paper presents an analysis of train screw coupling used mainly in Europe as mechanical
connection of wagons in train. An analysis of train breaks apart incidents revealed that less than
30 % of the cases were caused ...
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 ...
