The synergistic action and interplay of hydrogen embrittlement mechanisms in steels and iron: Localized plasticity and decohesion
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Component failures due to the hydrogen embrittlement (HE) were observed in different industrial systems, including high-pressure hydrogen storage tanks, aircraft components, high-strength alloy components, and high-strength ...
Multi-objective design optimization strategies for small-scale vertical-axis wind turbines
(Springer, New York, 2016)
Extracting energy from wind has been an interesting and serious topic over the last few decades and a lot of work has been done on the subject. This paper discusses in detail possible approaches to optimization of a somewhat ...
Digital Image Correlation Analysis of Vertically Loaded Cylindrical Ti-Implants With Straight and Angled Abutments
(Springer, New York, 2016)
The purpose of this study was to investigate the influence of the abutment angulation upon the strain distribution pattern for the vertical loading situation by means of the digital image correlation (DIC) method. In ...
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 ...

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. ...
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 ...
Primary control reserve of electric power by feedwater flow rate change through an additional economizer - A case study of the thermal power plant "Nikola Tesla B"
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Coal-fired thermal power plants (TPPs) had been generally designed to cover base loads of electricity consumption. Nowadays, they should be flexible to participate in the primary frequency control of electric system, ...
Possibility of Reducing the Overpressure of Shock Wave of Powder Gases around the Mortar
