  • Abstract
    With the aid of the two-state M-integral and finite element analysis, the asymptotic solution in terms of the complete eigenfunction expansion is obtained for three dimensional crack corner problems. The proposed scheme enables us to extract the intensity of the eigenfunction term from the far field data without resort to special singular elements at the vertex
