Abstract
A simplified method for calculating crack interaction suitable for mul ticrack arrangements is introduced. It is based on approximating the c rack-generated stress field by that produced by a pair of edge disloca tions of opposite signs with Burgers vector equal to the average relat ive displacement of the crack faces under given load.
