An overview of application of micromechanical models in ductile fracture analysis of welded joints
(Srpsko društvo za mehaniku, Beograd, 2020)
Fracture of welded joints has been an important research and industrial topic for a long time, having in mind the key role of welded joints in ensuring the safe operation and integrity of welded structures. This work ...
Bertolino-baksa stability at nonlinear vibrations of motor vehicles
(Srpsko društvo za mehaniku, Beograd, 2017)
Research of vehicle response to road roughness is particularly important when solving problems related to dynamic vehicle stability. In this paper, unevenness of roads is considered as the source of non-linear vibrations ...
Experimental and numerical analysis of flow field and ventilation performance in a traffic tunnel ventilated by axial fans
(Srpsko društvo za mehaniku, Beograd, 2018)
To investigate air flow in longitudinally ventilated traffic tunnels, a scaled model of a typical road-traffic tunnel with an appropriate ventilation system based on axial ducted fans, is designed and built in the Lab. The ...
On the influence of turbulent kinetic energy level on accuracy of k - epsilon and lrr turbulence models
(Srpsko društvo za mehaniku, Beograd, 2018)
This paper presents research regarding the influence of turbulent kinetic energy (TKE) level on accuracy of Reynolds averaged Navier-Stokes (RANS) based turbulence models. A theoretical analysis of influence TKE level on ...
Estimation of wind turbine blade aerodynamic performances computed using different numerical approaches
(Beograd : Srpsko društvo za mehaniku, 2018)
Although much employed, wind energy systems still present an open, contemporary topic of many research studies. Special attention is given to precise aerodynamic modeling performed in the beginning since overall wind turbine ...
Compressible flow through solar chimneys with variable cross section - an exact solution
(Srpsko društvo za mehaniku, Beograd, 2017)
Buoyancy driven, adiabatic and compressible flow in relatively high solar chimneys is treated in the paper analytically by using one-dimensional model of flow. General equations written suitably in a non-dimensional form ...
The brachistochronic motion of a vertical disk rolling on a horizontal plane without slip
(Srpsko društvo za mehaniku, Beograd, 2017)
This paper deals with the brachistochronic motion of a thin uniform disk rolling on a horizontal plane without slip. The problem is formulated and solved within the frame of the optimal control theory. The brachistochronic ...
Free vibrations of planar serial frame structures in the case of axially functionally graded materials
(Srpsko društvo za mehaniku, Beograd, 2020)
This paper considers the problem of modal analysis and finding the closed-form solution to free vibrations of planar serial frame structures composed of Euler-Bernoulli beams of variable cross-sectional geometric characteristics ...
