| Abstract: | The equivalent elastic moduli of bodies with orderly distributed cracks can be computed by boundary element method. A practical self-consistent scheme has been proposed in the consideration of the mutual interaction effects of the cracks. The influence of friction coefficients and orientation of cracks hat been investigated. Some computational examples have been given, and the results show that the proposed method is adequate and the scheme is efficient. |
