Bucket chain excavator: Failure analysis and redesign of the counterweight boom supporting truss columns
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The supporting truss of the counterweight boom is a vital part of the bucket chain excavator's (BCE) superstructure. The occurrence and propagation of cracks in the supporting truss columns' heads may lead to BCE collapse. ...
Condition and behaviour diagnostics of drive groups on belt conveyors
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Belt conveyors are complex systems with drive groups as functionally very important components. Their proper and reliable operational life is directly related to durability of the load-bearing steel structures. Drive units ...
Failure analysis of hydraulic turbine shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on ...
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 ...
The renewed TC12/ESIS technical committee - Risk analysis and safety of large structures and components
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The ESIS Executive Committee decided to nominate a new team for the leadership and management of the TC12/ESIS technical committee (TC), as well as update the TC name as "Risk Analysis and Safety of Large Structures and ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Influence of welded joint microstructures on fatigue behaviour of specimens with a notch in the heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, the results of determining the Paris law coefficients, C and m, are presented, based on the experimental data obtained by three-point bending testing of 8 welded joint specimens. The specimens were taken ...
Determining the crack acceptability in the welded joints of a wind loaded cylindrical steel shell structure
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Engineering critical assessment can be considered as a mandatory request in the civil engineering designing and manufacturing process. The paper is presenting the procedure for determination of crack acceptability based ...
Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
Failure investigation and reparation of a crack on the boom of the bucket wheel excavator ERS 1250 Gacko
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects ...
