In this paper, fundamental knowledge for fracture of rubber is summarized. Standardized rubber testing methods and fundamental understanding of fracture mechanics for rubber is briefly discussed. Tensile strength in standardized testing method is also reviewed from fracture mechanics point of view. Throughout this paper, the important role of hysteresis energy for rubber strength is highlighted.
