摘要：

In this study. interaction between a main crack and a surrounding layer of microcracks is considered. A stress field distribution induced during these interactions is obtained using a semi-empirical approach (SEA), which relies on the Green's functions. The effect of amplification and shielding on the resulting stress field is shown, herein, through a study of mode I stress intensity factor (SIF). To quantify these effects, orientations as well as positions of microcracks with respect to the main crack are taken into consideration. Finally, the obtained results are compared and agreed with those of other researchers. (C) 2004 Elsevier B.V. All rights reserved.
