The effect of the stress far field on the crack tip behaviour

A. PIVA

Abstract


The boundary value problem of an infinite purely elastic sheet with
a traction-free crack loaded with a uniform shear and biaxial tension at
infinity is solved. It is shown that the singular terms of stress and displacement functions are inadequate to predict the direction of initial crack extension. The independence of the J vector of the biaxial parameter is also proved.
