Resumen: Plane strain slip line fields for a range of elastic-plastic contained yielding problems have been constructed. These include cracks in homogeneous materials subject to both mode I and mixed mode loading. Fields have also been constructed for cracks on the interface between a rigid substrate and a perfectly plastic material, subject to mixed mode loading which may lead to matrix failure. On the plane of maximum hoop stress, fields for non hardening and moderate hardening rates can be interpreted as belonging toa single family which differ by a hydrostatic terrn (Q), but are deviatorically similar. The fracture resistance of these configurations can thus be unified by a constraint based fracture toughness relation ( J - Q).
