Simulation of Energy Absorption Effects during Helmet Collision with a Hard Obstacle
(Civil-Comp Press, 2010)
This paper presents a simulation model of the absorption effects during a helmet collision with a hard obstacle. It is based on a necessity to predict the undesirable consequences that may occur in the case of a helmet ...
True Stress-strain Curves for HSLA Steel Weldment - Iteration Procedure Based on DIC and FEM
(Elsevier, Amsterdam, 2020)
True stress-strain curves of HSLA steel welded joint regions were estimated by using numerical simulation of strains measured by DIC and special iteration procedure to match the results. Strains were measured at certain ...
Structural dynamic modification of a tubular collector
(Proceedings of the 5th International Congress of Serbian Society of Mechanics, 2015)
Dynamic modification of structures involves the transformation of an existing model in the
new one, which has better behavior and higher accuracy in comparison with the existing. The
main objective of a dynamic modification ...
APPLICATION OF FINITE ELEMENT METHOD FOR ANALYSIS THE PARAMETERS OF FRACTURE MECHANICS
(University of Belgrade Faculty of Mechanical Engineering, Belgrade, 2022)
When making mechanical components, geometric imperfections are common, which in certain cases can cause a weak spot or some form of crack. Depending on the intensity and position of the action of forces on the mechanical ...
Deformation and Stress Fields in Thin Metallic Partially Fixed Plate Induced by Electromagnet with Constant Flux Obtained by Analytical Method and FEM
(The First International conference on computational mechanisc (CM’04), 2004)
In the paper the behavior of thin elastic metallic partially fixed plate produced by
electromagnet with constant flux is considered. Plate is simply supported along three edges and
fixed along the fourth one. As ...
Analysis of the stress field in a model of pipe branches
(Proceedings of TEAM 2015, 7th International Scientific and Expert Conference of the International TEAM Society, 2015)
The aim of this paper is to analyze the stress field of
a complex geometry model of pipe branches loaded
with internal pressure of 10 bar. The analysis will be
done by comparing method of strain gauges and a
new one ...
Methods for numerical and experimental diagnostics of complex structures’ strength with special reference to model analysis
(Seminar Mechanics of machines and mechanisms- Models and Mathematical Methods, Mathematical Institute of SASA, 2020)
There are numerous examples of failure of steel structures. There are various causes,
such as error in design, error in production, error in exploitation or unexpected loads.
When failure occurs, standard series of ...
