DEVICE FOR INVESTIGATION OF KINETICS OF CRACK GROWTH

摘要

Device for investigation of kinetics of crack growth has volume filled with liquid that together with cavity of the sample forms chamber with closed volume, divider that separates the chamber from source of pressure and registration device. Divider is arranged as a movable ram that performs reciprocal motion. Character of changes in position of the ram determines the instant of a through crack coming to existence and rate of its propagation.
