A special finite element method (FEM) program to analyze three dimensional singular order of bonded dissimilar materials has been developed. It has been found that three dimensional stress singular order can be accurately determined by using this program for both single and multiple singularities. It has been also found that the three dimensional stress singularity of the interface corner of bonded dissimilar materials is different from that for both plane strain and plane stress cases. Three elastic parameters to express the effect of material combination on the three dimensional edge singularity have been also investigated. Based on the analysis by using the special FEM program, iso-counter graphs of the stress singular order at the three dimensional interface corner have been drawn for three typical interface corner models, which can be used as the database for determining the three dimensional singularity of bonded dissimilar materials.
