Coupled nonlineary problems in finite element analysis - a case study
Ivana Atanasovska, Dejan Momčilović, Meri Burzić, Tomaž Vuherer
Objavljeni znanstveni prispevek na konferenci
Oznake: kinetic energy absorber;railway;elastic plastic deformation;contact;finite element analysis;
The paper describes the Finite Element Method (FEM) analysis of elastic plastic deformation of steel tube impact absorbers for railway vehicles. Experiment investigation is used as a basis for FEM modelling and simulation. The developed FEM model includes material nonlinearity (plasticity), nonlinea ...

Methodology of determination the influence of corrosion pit on decrease of hydro turbine shaft fatigue life
Dejan Momčilović, Radivoje Mitrović, Ivana Atanasovska, Tomaž Vuherer
Izvirni znanstveni članek
Oznake: fatigue;fracture;turbine shaft;theory of critical distances;
This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaftflange transition section. The case study of hydraulic turbine shaft failure is used as the basis for this research. The quantification of the stress concentrators was accomplished by the usag ...
