Experimental Investigation of Foams Suitable for Motorcycle Protectors

Protectors of motorcycle riders should be light and safe. This work deals with the impact test of the shoulder protectors, which differ with the use of foams of different densities. The acceleration and displacement of an impactor having the mass of five kilograms were measure...

Comparison of detailed belt-cylinder interaction model with classical belt friction formula

This paper deals with a comparison of the classical belt friction formula, also called Euler-Eytelwein equation, with a detailed belt-cylinder interaction model. The belt friction is a typical pedagogical problem where the usage of equilibrium conditions is shown, but also have a practi...

Homogenization based two-scale modelling of ionic transport in fluid saturated deformable porous media

The paper deals with the homogenization and numerical modelling of deformable porous media saturated by two-component electrolytes. The model relevant to the microscopic scale describes steady states of the medium while reflecting essential physical phenomena, namely electrochemical interactions in a&...

Crack propagation prediction in aluminum friction welded joints

Integrated dual boundary element method – finite element method are applied. As well, the welding procedure simulation and the successive crack propagation evaluation are coupled. For AA 2024-T3 aluminium rolled sheets welded, the forging action of the tool shoulder is enhanced by impos...

Influence of temperature on foam used in motorcycle protective equipment

This paper researches influence of the temperature on a foam, which is used in motorcycle protective equipment. The impact test was carried out on samples, which were cut from the center part of the protector that is suitable to protect shoulder, elbow and knee areas. Its...
