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

A new type of finite element is introduced which embodies the inverse square root singularity present near a crack in an elastic medium. Using this element near the tip in two typical cracked configurations, stress intensity factors within 5 per cent of accepted values were obtained with meshes havi
A procedure has been developed to calculate the stress intensity factors from the displacements along any arbitrary crack tip radial line on a quarter-point singular finite element boundary. This procedure enables the conventional finite element method to handle surface and one-dimensional flaws wit
