摘要：
A closed-form solution has been developed to predict the effect of T-stress on the crack-inclusion interaction. As validated by several numerical examples, the approximate solution has satisfactory accuracy for different inclusion shapes and modulus ratios between inclusion and matrix under different T-stress levels. Thus the role of T-stress in crack-inclusion interaction can be predicted quantitatively. (C) 2006 Elsevier Ltd. All rights reserved.
