Abstract

Data from the ductile materials reported in Part I are compared to planar elastic results. The experimental and theoretical strains are markedly different both in angular distribution and in decay with distance from the crack tip. The distortional energy density data also differ with theory, in terms of angular distribution, but their radial behavior is closer to the inverse distance relation of elasticity. The total plastic energy release rate is inferred from the data; it is considerably in excess of the critical rate[Figure not available: see fulltext.]. This disparity is discussed in terms of the regions where energies are released.
