Microcrack interaction with a main crack

It is noted that calculations of the interaction between a main crack and two-dimensional microcracks surrounding the main-crack tip can be considerably simplified by using a point-source representation for the microcracks and a self-consistent scheme to determine the strength of these point sources...

Zusammenfassung:	It is noted that calculations of the interaction between a main crack and two-dimensional microcracks surrounding the main-crack tip can be considerably simplified by using a point-source representation for the microcracks and a self-consistent scheme to determine the strength of these point sources. The procedure is illustrated by a detailed analysis for two basic configurations: (1) a single microcrack of arbitrary orientation near a main crack which is subjected to combined mode I and mode II loading, and (2) two microcracks symmetrically disposed about a main crack which is subjected to purely mode I loading.
