This article is focused on the computational solution of the material tests and their evaluations. Problem deals with torsion low-cycle fatigue tests of steel specimens. [...]

Computer-aided engineering (CAE) represents the broad usage of computers for engineering problems. It includes computer-aided design (CAD) or computer-aided analysis (CAA [...]

Seven ductile fracture criteria are applied to simulation of cold forward extrusion and their performance in prediction of chevron cracks is presented. The criteria are i [...]

Paper is focused on comprehensive solution of probabilistic integrity assessment of pressure vessels. Engineering criteria was fully respected during solution, however fr [...]

Abstrakt: In all power plants (classical and nuclear) are used safety relief valves. After opening of this ones the mass of fluid (gas or steam) begin to move with very h [...]

Specific feature of the nuclear power plants is in comparison with coal fired plants the break postulation of each high energy piping. Fluid system is considered as high- [...]

Abstrakt:

Abstrakt: Dynamic effects of seismic excitation and of the steam line break in the weld of the steam pipe and the steam collector during an earthquake are analyzed. Gener [...]

The paper deals with material models calibration from experiment tests on cylindrical bar. There are calibrated four ductile damage criteria, which seem to be generally w [...]

The aim of this contribution is comparing the results of the solution of steam piping response to the guillotine rupture at the variation of some parameters of the select [...]

Paper focuses on possibilities of transient processes modelling at pressure pipe system of a non-nuclear part of a certain power plant and summarizes the results of relat [...]
