Abstract
Unlike the classical crack extension energy release rate, the crack mo uth widening energy release rate is related to the Mode I stress inten sity factor by application of the principle of virtual work. Solutions are derived for cracked beams and pipes while the method applies in a straightforward manner to other crack configurations. The results are shown to agree well with those available in the open literature. (C) 1998 Elsevier Science Ltd. All rights reserved.
