Failure analysis and redesign of the bucket wheel excavator two-wheel bogie
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
This paper discusses the cause of the failure in the vital part of the crawler travel gear of the bucket wheel excavator (BWE) - two-wheel bogie (TWB). The results of the finite element analysis (FEA) point out that the ...
Failure analysis of the combat jet aircraft rudder shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper analyzes failure causes of the combat jet aircraft rudder shaft (RS) which occurred during the flight mission. A finite element method (FEM), utilized to determine the stress state of the RS subjected to hinge ...

Load-bearing steel structure diagnostics on bucket wheel excavator, for the purpose of failure prevention
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate ...
Analysis of the stress state of multilayer pressed joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper presents the results of analytical, numerical and experimental research of the stress-strain states of multilayer pressed joints in the field of elastic deformations. Suitable numerical (FEM) and analytical ...
Calculated and experimental analysis of cause of the appearance of cracks in the running bogie frame of diesel multiple units of Serbian railways
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this paper an analysis of possible causes of crack occurrence on reconstructed diesel multiple units (DMU) exploited on sideline in Serbia was performed. Analyzed DMU were designed in the sixties of the last century in ...
