Abstract

A method for analyzing an interface crack problem is proposed based on Body Force Method. In order to treat the so-called oscillatory stress and displacement field in the vicinity of the crack tip strictly, a new basic density function for an interface crack is introduced. In addition to the formulae for an interface crack problem, many problems of the elastic bi-material con- taining arbitrary cracks are solved numerically by using a personal computer and the results are demonstrated in tables and graphs. 1 Introduction The Body Forc
