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 [...]

A two-parameter fracture mechanics method is applied to small cracks near a stress concentrator. The small crack in the present contribution is considered as crack influe [...]

This article shows: 1. Some studies of a low-cycle material fatigue caused by cyclical contact between two spheres with the same diameters. The spheres are made up from m [...]

Fatigue is a process of permanent progressive changes in the structure of a material exposed to cyclic loading. This paper describes the strain development in concrete st [...]

The paper deals with the approach to modelling and optimization of turbine generators whose bodies have primarily non-symetrical geometry and stiffnesses in two perpendic [...]

The article gives the general view to the detection of defects (rather the cracks) of mechanical structures through initializing and receiving so-called Rayleigh waves, w [...]

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

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 [...]

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 [...]
