Solution for consolidation and retrofitting a historical steel bridge
(Elsevier Science Bv, Amsterdam, 2022)
Sustainable development is a fundamental goal of the European Union and seeks to meet the needs of the present, without compromising the future. The rehabilitation of historic steel constructions and old steel bridges in ...
Fatigue crack growth in locking compression plates
(Elsevier Sci Ltd, Oxford, 2022)
Fatigue crack growth in orthopaedic locking compression plates (LCP), under four-point bending, has been simulated by the extended finite element method (xFEM) to assess LCP optimal geometry in respect to remaining life. ...
Structural Integrity Analysis of a Kaplan Turbine Cover
(Elsevier Science Bv, Amsterdam, 2022)
During recent revitalization of Kaplan turbine aggregate made of structural steel St 3 (GOST standard), experimental investigation was performed. Base metal and welded joints were tested by non-destructive methods (NDT), ...
Influence of the air pressure and oil amount to the temperature of the high-speed bearings lubricated by oil mist
(Emerald Group Publishing Ltd, Bingley, 2022)
Purpose The purpose of this paper is to improve the lubrication and remove as much as possible of the heat generated in the bearing assembly, embedded in the jet engine. Design/methodology/approach To determine the necessary ...
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 ...
Numerical Simulation of Fatigue Crack Growth in Different Welded Joint Zones
(Springer Science and Business Media Deutschland GmbH, 2022)
This paper involves the numerical analysis of fatigue behaviour of welded joints made of steel SA-387 Gr. 91, with special attention devoted to its regions, which have very different mechanical and fatigue properties. ...
Thermal analysis and phase changes of mechanochemically activated sodium carbonate
(Elsevier, Amsterdam, 2022)
Sodium carbonate is a well-known material for being used as a good sorbent of carbon dioxide from the atmosphere, and as such has gained increasing importance in environmental protection. In order to enhance its sorption ...
Differences in attitudes of operators and managers on risk management of pressure equipment
(Taylor & Francis Ltd, Abingdon, 2022)
Objectives. Previous research indicates that models for risk assessment of pressure equipment have not sufficiently or adequately integrated indicators of human factors and organizational factors. Methods. The goal of this ...
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 ...
Comparison of Tensile Properties of Carbon/Epoxy Composite Materials with Different Fiber Orientation Using Digital Image Correlation
(Springer Science and Business Media Deutschland GmbH, 2022)
Due to its remarkable qualities, carbon fiber epoxy composite sandwich panels are used in a variety of engineering applications. The goal of this research is to use tensile testing and a full-field non-contact 3D Digital ...
