An effective method for analyzing interaction behaviors of multiple through-cracks subjected to complex loading

The improved body force method is proposed for analyzing interaction behaviors of arbitrary multiple through-cracks under complex loading. Two improvements are made: One is the adoption of relative coordinate transformation against each crack centre and the other is the treatment of integral singurality by Proposed indirect method.In comparison with available data published, the results obtained show that the proposed method is an effective one for analyzing interaction behaviors of muitiple through-cracks subjected to complex loading.
