Izazovi budućih istraživanja u oblasti industrijske bezbednosti / Challenges of future research in the area of industrial safety
(Institut za ispitivanje materijala, Beograd, 2015)
In today's turbulent business conditions, characterised by rapid technological development of a 'post industrial' society, in which new technologies result in new risks, safety management of complex techno-socio-ecological ...
Shear strength testing of hardfaced samples using special tool on an universal testing machine
(Institut za ispitivanje materijala, Beograd, 2015)
Complex working conditions of forging dies are the most frequent causes of their damage, requiring suitable hard facing repair procedures. The method of determining the bond strength between the hardfaced layer and the ...
Crack resistance of aluminium alloy friction stir welded joint
(Institut za ispitivanje materijala, Beograd, 2015)
Charpy testing is conducted on a high-speed data acquisition instrument, using instrumented pendulum to separate energies for crack initiation and propagation. The J-R curves are used to determine JIc, as the measure of ...
Friction stir welding of aluminium alloys - T joints
(Institut za ispitivanje materijala, Beograd, 2015)
The paper presents results of research on the possibility of producing T-joints of aluminium alloys without defect by friction stir welding process. Friction stir welding process is applied in welding T-joints of aluminium ...
Final stretch zone width determination for MP35N multiphase alloy
(Institut za ispitivanje materijala, Beograd, 2015)
This paper presents an experimental elastic-plastic fracture behaviour analysis in order to evaluate a resistance of the aged and unaged MP35N alloy to stable and unstable crack growth. MP35N fracture behaviour has been ...
Advantages of friction stir welding over arc welding with respect to health and environmental protection and work safety [Prednosti zavarivanja trenjem sa mešanjem u odnosu na elektrolučno zavarivanje - Zaštita zdravlja i životne sredine i bezbednost na r
(Institut za ispitivanje materijala, Beograd, 2015)
In modern industrial production, every manufacturing and assembly process should be assessed with respect to its influence on the environment. For a company that invests in a new process, a careful analysis of HSE problems ...
Determining reliability functions of steam turbine in power plant 'Nikola Tesla, block a4'
(Institut za ispitivanje materijala, Beograd, 2016)
Determination of reliability indicators of steam turbine system in the thermal power plant 'Nikola Tesla, Block A4'during useful life period is based on a ten-year operational database. By implementation of mathematical ...
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 ...
Assessment of integrity of pressure vessels for compressed air
(Institut za ispitivanje materijala, Beograd, 2021)
Fracture mechanics approach for structural integrity assessment is described in the case of pressure vessels for compressed air. The results of non-destructive testing indicated unacceptable defects on the vessels and set ...
An analysis of random mechanical failures of bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2015)
In this article random mechanical failures of bucket wheel excavator at open cast mine "Tamnava Zapad" are analysed. Random mechanical failures of mining equipment may represent an important factor in coal production because ...
