The stress field near the notch tip of an incompressible rubber-like specimen under the condition of plane strain

摘要

Using Gao's constitutive relation, the stress field has been analyzed near the notch tip and the crack tip of an incompressible rubber-like specimen under the condition of plane strain. The asymptotic equation of the notch tip field is solved numerically; the stress and strain singularities are calculated for various notch angles and different material constant values; the stress variation with the angle coordinate is also analyzed.
