S-N curve, the most effective and essential data to estimate a fatigue life of rubber is revealed with the rubber elasticity theory using material's characteristic constants, such as modulus, strain energy release rate, intrinsic flaws and the crack growth intensity coefficient. Mechanical properties of rubber are thus occupied strongly by rubber elasticity as well as viscosity over considerably high strain fields.
