Abstract

Accumulated cyclic deformation is considered as a measure of the fatigue life of a construction and (BiSb)Te films have been used to measure it. These gauges can be used for the estimation of both the stress spectrum acting on a material and the remaining service life of a material. The results obtained during the investigations of 2024T3 and 7075T6 alloys show that the kinetics of cyclic deformation accumulation has a definite regularity. The accumulated process consists of four stages, each allowing some judgement to be made concerning the degree of fatigue damage of the material.
