Abstract

The possibility to evaluate the mechanical state of weldments, their remaining life and prefracture stage diagnostics under multi-cyclic fatiguing on the basis of measurement and analysis the displacement vector fields by TV-optical method is shown. Measurement conditions of the displacement fields in the vicinity of the crack tip and fields evolution under cyclic tension are described. The criteria these characterize a fatigue failure accumulation at the mesoscale level are given.
