Changing the structure of concrete after exposure to frost
(Faculty Of Civil Engineering Subotica, 2014)
Concrete testing can be done at micro, mezzo and macro level. Tests at the macro level are the most common and are the ultimate engineering approach, and include testing and comparison of quantities such as commpresive ...
Gas cylinder rupture induced by local corrosion damage
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
Commercial gas cylinders are common type of pressure vessels in many health care and technical facilities. Unexpected
failures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
Simulation of the kinematic hardening of AISI 316 steel by nonlinear finite element analysis
(Serbian Society of Mechanics and Faculty of Technical Sciences Novi Sad, Serbia, 2015)
The coupled non-linear transient calculation is performed and explained in order to simulate the kinematic hardening behavior of AISI 316 steel and the Finite Element Method (FEM) is used for presented simulation. The ...
Feasibility Analysis for Repair of Large Diameter Hydro Turbine Shaft Based on Weldability Test and Welding Cycle Simulation
(Advanced Materials Research, 2019)
Turbine and generator rotors and shafts undergo high stresses during regular working life
and, from a safety and operational aspect, are the most significant components of a power
generation system. Depending on the ...
The influence of grooves on the behavior of steel tube shock absorbers
(Proceedings of the 7h International Congress of Serbian Society of Mechanics, Sremski Karlovci, Serbia, 2019)
Major function of railway vehicles absorbers is to absorb energy through controlled deformation during frontal rail vehicle collisions. The results presented and discussed in this paper is a part of the research of one ...
Theory of critical distances in analysis of the influence of tooth profile on gears bending capacity
(5th International Conference on Power Transmission BAPT2016, 2016)
The fatigue cracks and failures in tooth roots are still one of the most common problems in gear pairs operation.
Therefore, the application of new methods and up-to-date calculation procedures is welcome. This paper ...
Stress concentration factors in re-evaluation of design solution
(Serbian Society of Mechanics and Faculty of Technical Sciences Novi Sad, 2015)
The failures of various parts of mechanical systems in powe industry are the lessons that should be learned thoroughly. Every behaviour of structure close to design encelope must be ecxamined carefully in order to minimize ...
Development of the universal tool for testing of tensile properties of hexagonal steel wire mesh for civil engineering
(Savez inženjera metalurgije Srbije, Beograd, 2018)
The developing of the universal tool for testing of tensile properties of hexagonal steel wire mesh for civil engineering is described in this paper. The developed tool allows repeated testing of hexagonal steel wire mesh ...
Modal analysis of the hydro turbine shaft with cracks
(Abstracts of 14th International conference Dynamical Systems - Theory and Applications, 2017)
The design process for the elements which are the parts of the structures and equipment in power industry includes both of stress and strain state calculations, as well as an analysis of natural mode shapes and frequencies. ...
O aspektima modeliranja temeljnog nosača i tla za FEM analizu
(GEOREKS 2010, IV regionalni kongres studenata geotehnoloških fakulteta, Vrnjačka Banja, Srbija,, 2010)
U ovom radu su prikazani aspekti modeliranja izdvojenog temeljnog nosača i tla za uticaj statičkog opterećenja. Temeljni nosač je razmatran primenom linijskih, površinskih i prostornih konačnih elemenata, dok je tlo ...
