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
