A&met-The paper deals with the &rite element computation of the crack closure integrals (CCIs) and the stress intensity factors (SIFs) under mechanical and/or thermal loadings, which give rise to forces at nodes close to a crack tip region. Four examples are presented to illustrate the usefulness of

modified crack closure integral method with square-root stress singularity elements is given for calculation of strain energy release rate for an in-plane extension of a crack. Case studies are presented to illustrate the improvement in accuracy.
A general method for boundary element-crack closure integral calculation of three-dimensional stress intensity factors is presented. An equation for the strain energy release rate in terms of products of nodal values of tractions and displacements is obtained. Embedded and surface cracks of modes I,
