The influence of corner singularity on crack behaviour for a threedimensional structure is described in this paper. The distribution of stress singularity through the thi [...]

V příspěvku jsou uvedeny některé výsledky výzkumu MKP modelování šíření únavových trhliny v podmínkách smíšeného módu namáhání. Pro simulování r [...]

Fracture behaviour of concrete is studied using two-phase material model. Propagation of a single macrocrack in hardened cement paste (matrix) and aggregate (particle) is [...]

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- [...]

The aim of this paper is to investigate the beginnings of crack propagation from sharp V-notches. Stress distribution around the tip of a V-notch is described on the basi [...]

This paper presents a simulation of 3D curved crack propagation in a steam turbine blade lock. These fatigue cracks are often initiated near a blade root contact zone. Tw [...]

This contribution deals with reliability of railway wheels as influenced by the occurrence of impaired limiting material strength. Results are presented of material inves [...]

The article is a contribution to numerical simulations of pitting arise phenomena on the gear teeth. The basic assumption of the presented simulations was that pitting (p [...]

A substantial number of experimentally based works indicate the changes in crack propagation direction on bi-material interface in composite laminate materials. The paper [...]

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

The contribution discusses possible approach for the formulation of fracture criteria for the general stress concentrators – especially a surface crack terminating at t [...]

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 [...]

Cyclic tests with the maximum force in a cycle Fmax = 5,5 kN and the cycle asymmetry ratio R = F min / F max = 0, 1 were carried out on fiat specimens of 5mm in thickness [...]
