15.
The contribution deals with the modelling of the rolling contact between the wheel set of the railway vehicle and the curved railway and subsequently with the lateral mot [...]
16.
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 [...]

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- [...]
20.
To the interpretation of crack growth, it is substantial to estimate the plastic region geometry in front of a crack. Performed here is a study for predicting crack growt [...]

Zelenka, J.
This article describes the method of modelling the operation of a unit of the 680 series on a concrete section of the corridor of the Czech Railways and the height and di [...]
22.
A substantial number of experimentally based works indicate the changes in crack propagation direction on bi-material interface in composite laminate materials. The paper [...]
