Abstract

This paper introduces a new method to solve the singular stress strain field near a notch-tip in rubber-like materials. The constitutive relation used herein is valid even when the strain tends to infinity. The singular field is divided into shrinking sectors and expanding sectors for which the asymptotic equations are derived separately. The solution to the expanding sector is obtained analytically while that for the shrinking sectors are solved numerically. The singular behavior of the notch tip field is revealed clearly.
