The large deformation analysis of a hyperelastic tensile test sample

This example shows the static analysis of a tensile test sample made of rubber. The dimensions of the sample are shown in the following figure. The thickness of the sample is 1.5mm. Using the symmetry, only 1/8 of the sample is analyzed. After solving the 1/8 model, the results of the full model can be … Continue reading The large deformation analysis of a hyperelastic tensile test sample

The stress-strain curve of rubber material stiffened by carbon fiber

Fig.1. Illustration of the discretization and BCs A 2D model is created. Plane elements and beam elements are used to discretize rubber material and carbon fiber, respectively. To ensure that rubber and carbon fiber deform together (no slipping), plane elements and beam elements share common nodes. A concentrated force (the red arrow in Fig.1) is … Continue reading The stress-strain curve of rubber material stiffened by carbon fiber
