| 摘 要： | The response of cracked bodies subjected to loading was investigated bythe boundary element method in this paper.The two-law elastic-cohesive-softeningmodel was used for crack propagation analysis.The interface conditions foruncracked,craze,open crack,adhesive crack and slid crack parts were discussed andthe corresponding incremental iteration algorithm was given.A simplified damagepropagation model was presented.The technique has been applied to some specificexamples which give the evidence that the method is satisfactory and efficient.
