Abstract
This paper proposes a complete analytical solution for stress field near a crack-tip in closed form to analyse the effects of load biaxiality and is concerned with the following problems: stress intensity factor of pure type-I and type-II fracture; patterns of maximum shear isostats (isochromatic fringe patterns); patterns of octahedral stresses σ i and small-scale elasto-plastic stress field; the direction of initial crack extension and the biaxial effects on the crack with a blunt tip.
