Model analysis of bucket wheel excavator SchRs 630 strength
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The possibilities of testing real constructions are often limited, especially in case of large constructions. The idea of model testing is to create a sub-scaled model in order to anticipate the behavior of the real ...
Experimental and numerical cross-correlated modal analysis of the floor structure dynamics in a thermal power plant
(Institut za ispitivanje materijala, Beograd, 2015)
This article presents search methodology after the cause of excessive floor vibrations in a thermal power plant control room. The floor structure is a composition of a steel grillage and concrete slabs at 12 m level above ...
Unapredenje industrijske bezbednosti kranskih kabina / Industrial safety improvement of crane cabins
(Institut za ispitivanje materijala, Beograd, 2015)
Cranes significantly contribute to efficient work progress but also have a great potential to cause large life and financial losses. Cranes today do not meet the needs of large proportion of operators, therefore making ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel
(Institut za ispitivanje materijala, Beograd, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Remaining strength of API J55 steel casing pipes damaged by corrosion
(Elsevier Sci Ltd, Oxford, 2020)
Experimental investigation of the integrity of casing pipes, used in the oil drilling rigs, withdrawn after about 70,000 h of service, has been conducted, together with numerical simulation. Pipes were manufactured by the ...
Stress intensity factors numerical calculations for two penny shaped cracks in the elastic solid
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In the face of enormous costs of developing new aircraft, high fuel prices, increasingly demanding environmental standards, harsh economic race and the fight against competing manufacturers, today's aviation is adapting ...
Human factor risk management procedures applied in the case of open pit mine
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Risk management aims to provide a controlled work environment to ensure the safe operation of the high-risk systems. It is a dynamic process which work in a continual state of change. The issue of human factor risk and ...
Development and Improvement of Numerical Models of Welded Joints with Multiple Defects
(Trans Tech Publications, 2023)
This paper presents the development of numerical models which were used to simulate
the behaviour of welded joints containing different combinations of multiple defects under tensile
loads. Four representative combinations ...
Numerical simulation of titanium alloy hip replacement implants behaviour under static and dynamic loads
(HEMIJSKA INDUSTRIJA (Chemical Industry), 2023)
This paper presents development of numerical models for simulation of the behaviour of titanium alloy hip implants under static and dynamic loads, which is a part of extensive research involving the structural integrity ...
