Abstract

International audience; Based on the finite element method, the wave finite element method (WFE) permits to analyze the dynamics of a periodic structure by using a wave decomposition of one period. This method reduces the number of DOF and it has advantages in calculation time. However, [...]

Abstract

The vibration transmission to the cooled goods within a refrigerator is a usually neglected field of interest. Previous studies however show that biochemical properties can be affected by continuous exposure to vibration. Optimal storage conditions necessitate protection against UV [...]

Abstract

The energy-based fatigue model presented in this work overcomes different shortcomings of existing model approaches, such as the need of separated assumptions for constant life diagrams. By using the range of the normalised strain energy density and a probabilistic based mode interaction [...]

Abstract

The cyclic impact force between a reed valve and the seat plate is the main reason of the valve failure in many thermo-technical devices as compressors, engines, etc. According to experimental observations the latter is due to fatigue and usually occurs in the leading part of the [...]

Abstract

Injection molding is undoubtedly one of the most widely used manufacturing process for polymers [1]. Due to its advantages over other processing techniques in terms of good surface finish, the ability to process complex parts without the need of secondary operations and low cost for [...]
