Abstract

If a homogeneous, isotropic, linearly elastic solid containing a plane crack is loaded so that the analytically computed singular parts of the near-tip stresses are symmetric relative to the plane of the crack, one might perhaps expect the crack to propagate in its own plane, when the pertinent stress intensity factor reaches a critical value. Experimental evidence often shows, however, the phenomena of skew crack propagation and crack bifurcation, especially for rapidly propagating cracks. Although it has been suggested by several authors that elastodynamic effects play an important role in crack branching, analytical investigations have only recently become available for antiplane strain. The computation of the elastodynamic fields has presented the principal obstacle.
