A study on stress intensity factors and singular stress fields of three-dimensional interface crack

摘要

By using the finite-part integral concepts and limit technique, the hypersingular inte- grodifferential equations of three-dimensional(3D)planar interface crack were obtained; then the dominant-part analysis of 2D hypersingular integral was further used to investigate the stress fields near the crack front theoretically, and the accurate formulae were obtained for the singular stress fields and the complex stress intensity factors.
