ON THE SECONDARY FORCES IN A SEMI-INFINITE MEDIUM CONTAINING AN EDGE DISLOCATION, A CIRCULAR CUT AND A CIRCULAR HOLE (CONTINUED REPORT)

摘要

To continue the work presented in the previous paper [1] the interaction between a circular cut and a circular hole, and an edge dislocation placed on the glide plane inclined to the straight boundary, which are arranged in the order of cut-edge dislocation-hole on the x-asis in a semi-infinite medium is investigated on the basis of the Airy stress function. Results obtained by numerical calculation indicate that, for the region near interface, the interactions are greatly affected by the geometrical relations. It is also interesting to note that the dislocation has an unstable equilibrium position at some intermediate distance from the hole as same with Figs. 6 and 7 in the previous paper. Moreover, it may be no ted that the relative equilibrium position is effected by the inclination of glide plane when a(0)/b is small. [References: 2]
