METHOD OF DETERMINATION OF SURFACE RESIDUAL STRESSES Russian patent published in 2000 - IPC

Abstract RU 2155952 C2

FIELD: method of nondestructive test. SUBSTANCE: method may be used for diagnostics of construction and parts of machines. Method includes heating of surfaces by continuous flux of radiation which causes residual deformations. After heating and cooling, deformations are determined by one of precision methods. Residual stresses are judged by deformations. Residual stresses are determined without destruction and loading of object under operating conditions. EFFECT: enhanced efficiency.
