Modelling the Nonlinear Shear Stress-Strain Behavior of a Carbon Fabric Reinforced Polyphenylene Sulphide From Rail Shear and ((45°,-45°))_(4s) Tensile Test

摘要

In this article, the nonlinear shear stress-strain relationship of a carbon fabric-reinforced polyphenylene sulphide is investigated by performing and comparing both the [+45°/-45°]_(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.
