Fretting damage to fuel rods reduces the service lives of the fuel assemblies and therefore increases reactor operating costs. The future development of fretting-resistant spacer grids necessitates the investigation of fretting behavior by means of model ... see more

The fretting behavior of nuclear fuel assemblies is influenced by a number of parameters. One of these is the fit between the fuel rod and the spacer grid, which changes during the fuel residence time in the core. The influence of fit on fretting has been... see more

The present paper includes the first part of an investigation of the complex braking process during the braking of railway vehicles, using transient thermal FE models with temperature dependent material properties. In the development of the geometric mode... see more
The paper includes the second part of an investigation of the braking process of railway vehicles, dealing with the temperature distribution of a brake block in various load cases and the FE analysis of the phenomenon of thermal elastic deformation. Therm... see more

The dissolution process of a CO2 gas bubble undergoing adiabatic free oscillation is investigated by coupling bubble dynamics with convective diffusion mass transport in the liquid phase. The minimum equilibrium radius necessary to the adiabatic free osci... see more
