BOUNDARY-ELEMENT ANALYSIS OF DISSIMILAR MATERIALS AND INTERFACE CRACK

The highly-accurate BEM elastostatic program, which is especially usef ul for the analysis of dissimilar materials and interface cracks, is i ntroduced in brief. By using this program, we can deal with the elasto static poblems of isotropic or orthotropic dissimilar materials and al so the bonded residual stress due to the mismatch of material constant s. This paper shows some applications of the BEM program to the analys is of dissimilar materials and interface cracks considering the residu al stress quantitatively, and also shows the method to evaluate the st rength of dissimilar materials based on the interfacial fracture mecha nics. Some experimental results and the evaluation on the strength of dissimilar materials are also presented.
