On biomimetics in machine elements design
(Manipal University Jaipur, India, 2019)
The aim of the paper is to point up the possibilities of biomimetics principles in the machine elements design. During last decades, the new requirements in machine elements design are placed in front of the experts. The ...
Common failures in aluminothermic welding process and proposal for their prevention
(University of Zagreb, Faculty of Metallurgy, 2018)
Aluminothermic welding of rail is still a unique method for joining the rails because of its flexibility
and ease of performance, both during the reconstruction and construction of a new track, as well as
in the ongoing ...
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 ...
Comprehensive approach to weld repair on elements of power transmission – case study for hydro turbine shaft
(Proceedings of the The 4th IIW South – East European Welding Congress, October, 10-13, 2018, Belgrade, 2018)
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 ...
Neural network model for the condition assessment of hydro turbines
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
During regular operation, hydro turbine elements have complex operating conditions. In order to prevent major failures, among other common preventive measures, it is necessary to make a useful model of hydro turbine. ...
Analysis of contact fatigue coupled with geometry and material nonlinearities by Theory of critical distances
(2nd Conference on Nonlinearity, Belgrade, 2022)
The contact fatigue is a localized phenomenon that occurs in highly
stressed local zone of the material under the loaded contact region and as such is
highly nonlinear problem. This phenomenon exists in almost all real ...
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 ...
Geometric optimization of shaft transition zone based on stress-strain analysis of nature inspired design
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
The presented research primarily considers with the geometric solutions that Nature has optimized. In the study presented in this paper, the nature inspired transition shapes are used in the research of innovative design ...
Experimental determination and numerical validation of the critical value of the J-integral ofa low carbon microalloyed steel for elevated temperature application
(VIII INTERNATIONAL CONGRESS ENGINEERING, ENVIRONMENT AND MATERIALS IN PROCESS INDUSTRY EEM 2023, 2023)
To evaluate the behavior of a homogeneous material in the presence of a crack-type defect, the
value of the critical stress-intensity factor, KIc, was determined as a measure of the fracture
toughness of the tested steel ...
