| Abstract: | The mixed mode fracture problem of semielliptical surface crack in a plate is investigated by means of the three dimensional singular element method, in which the singular tlement is constructed on the basis of the asymptotic series of stress and displacement fields in front of the crack edge.It is the first time that the stress intensity factors K 11 and K111 are presented, for the cases that the finite plate are subjected to shearing and twisting loads, and the influences of thickness and width of the paltes are studied. Authors also discuss the characters of this method in this papers. |
