Mang] Dynamic interaction between a macrocrack and a collinear, neighboring microcrack is investigated. The mathematical formulation presented here is two-dimensional, and for a state of antiplane strain. A time-domain boundary integral equation method is presented to calculate elastodynamic stress intensity factors generated by the incidence of stress (or displacement) pulses on single cracks and systems of two collinear cracks. As a check of the time-stepping technique presented here, numerical calculations have been carried out for pulse incidence on a single crack, and the results have been compared with those of other authors. For macrocrack-microcrack configurations the variation of the effective stress intensity factors at the tips of the macrocrack with time, with the microcrack location, and with the microcrack size will be displayed and discussed.
