β¦ Synopsis
The Reciprocal Work Contour Integral Method of Stem, et al. is extended so that computation can be made of fracture mechanics parameters at the comer formed by arbitrarily oriented stress free surfaces. Two numerical examples are given. In one, results are compared to those obtained using an overdetermined collocation technique.

## Abstract A series of commercial polystyrenes was tested using an instrumented impact tester to determine the fracture toughness __K__~__c__~ and critical strain energy release rate __G__~__c__~. Over the range of __M__~__w__~, 201,000 to 336,000, __K__~__c__~ increased from 1.38 MN/m^3/2^ to 1.7
Typical bimaterial interfaces are non-planar due to surface facets or roughness. Crack-tip stress fields of an interface crack must be influenced by non-planarity of the interface. Consequently, interface toughness is affected. In this paper, the crack-tip fields of a finite crack on an elastic/rigi
