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&...

The Biot-Darcy-Brinkman model of flow in deformable double porous media; homogenization and numerical modelling

In this paper we present the two-level homogenization of the flow in a deformable double-porous structure described at two characteristic scales. The higher level porosity associated with the mesoscopic structure is constituted by channels in a matrix made of a microporous material cons...

Hyperplastic material model with damage for woven composites

A hyperplastic material model with damage was developed in order to describe the non-linear mechanical behaviour of woven composites. The proposed model is based on thermodynamic principles and considers the additive decomposition of logarithmic strain in accordance with assumed finite strain...

Optimization and Testing of RSI

This paper deals with the Relative Strength Index (RSI), a popular oscillator. It answers the question whether – almost 40 years after its publication – the RSI can be still useful in trading. To answer this question, we compare four strategies: RSI with recommended parameters...
