In this paper, we deal with the mechanical behavior of elastomeric materials subjected to high cyclic loading in cases of high strain. First, a methodology for material parameter identification is used for a constitutive visco-hyperelastic law with discontinuous damage, modeling the Mullins effect. Then a fatigue model characterized by a strain energy density-based criterion is proposed and implemented in the finite element code, Code-Aster [1]. Two kinds of elastomer are considered, an incompressible rubber and an expanded compressible polyurethane. Cyclic tensile tests were performed to identify material fatigue parameters. Finally, a numerical application using a finite element model is presented. This model is a plate perforated by a ?6 mm hole for the first sample and a ?10 mm hole for the second one. The results obtained from the finite element model are compared to experimental results. 相似文献

In this paper, we deal with the mechanical behaviour of elastomeric sole shoes subjected to bending. First, a methodology for material parameter identification is described for a visco-hyperelastic constitutive law with discontinuous damage, modelling the Mullins effect. This constitutive law was implemented in the finite element software CODE-ASTER (Abbas and Baranger 2010). Then, numerical results of the bending behaviour of a simple geometric shoe sole model are compared to experimental measurements obtained with a stereoscopic vision system. Finally, an industrial application of dynamic bending sole shoe is presented and experimental results and simulated load history are compared. 相似文献
