Abstract
Three kinds of brittle material - gabbro-diabase, gray iron of two modifications and fused quartz - have been tested under uniaxial strain conditions of shock loading. The local probing of the free surface of targets by using interferometric technique allows to determining the criterion for initial stage of brittle damage in the form of threshold value of local stress. This stress corresponds to appearance of horizontal step at the front of compressive pulse which evidences the nucleation of local source of damage.
