METHOD FOR DETERMINATION OF DIMENSIONS OF FATIGUE ZONE OF PRE-DESTRUCTION

摘要

Method for determination of dimensions of fatigue zone of pre-destruction is in determination of distribution of value of plastic deformation along axis X that coincides with axis of concentrator of stresses and determination of distance from edge of object of control (top of stress concentrator) to specific point of the distribution that determines dimension d* of fatigue zone of pre-destruction. One uses direct method of determination of value of plastic deformations and distribution of those is measured on surface of object of control in contact-less way.
