摘要：
A new fracture criterion based on the assumption that brittle fracture occurs when the strain gradient reaches its limiting value is formulated. The presence of a strain gradient at the boundary of a body's temperature drop is shown analytically. The results of an experiment with specimens under an abrupt change in temperature are presented.
