Modelling the nonlinear shear stress–strain behavior of a carbon fabric reinforced polyphenylene sulphide from rail shear and [(45°,−45°)]_4s tensile test

Abstract

In this article, the nonlinear shear stress-strain relationship of a carbon fabric-reinforced polyphenylene sulphide is investigated by performing and comparing both the [þ458/2458] ns tensile test and the three-rail shear test. First, quasi-static and hysteresis tests are performed to obtain the data necessary for the material model. Then, the material constants are optimized by comparing finite element simulations with the data derived from the experiments. The conducted experiments are simulated and the results are compared with the experiments, with excellent correspondence.

A Material Model for FE-Simulation of UD Composites

“…(4) where G 12 * is the gradient of the loading/unloading cycle. In [1][2][3] an alternative method for calculating the parameters C 1 , C 2 , C 3 and C 4 is presented based on an optimisation strategy.…”

“…The method presented in [3] is used for this material model. It considers plasticisation and damage.…”

“…A material model which can handle the typical stress-strain behaviour of a [+45°/−45°] tensile test is presented in [3]. This method is also used in this paper but with some enhancements to cope with loading and unloading.…”

“…Nonlinear material behaviour of fibre-reinforced materials in shear was observed by various authors [1][2][3][4][5]. A material model which can handle the typical stress-strain behaviour of a [+45°/−45°] tensile test is presented in [3].…”

“…Thus, very few works highlight the behavior of carbon fabric PPS laminates 8,9 and a few authors investigated the influence of high temperatures on the behavior of UD-reinforced PPS matrix.…”
