Stress analysis of two different types of cracks due to fatigue of cord-rubber composites has been carried out using micromechanical 2D and 3D finite element analysis. The von-Mises/Tresca stresses that characterize the severity of crack tips in rubber composites has been computed from the finite element analysis. Numerical results of von-Mises/Tresca stress values are presented for two crack types and crack sizes under transverse strain and shear strain loading conditions. The results presented demonstrate that crack type, loading, and crack size have a strong effect on the values of von-Mises/Tresca stresses. The results of the von-Mises/Tresca stress should help in estimating the severity of local failures in cord-rubber composites.
