IDENTIFICATION OF SINGLE-AXIS HARMONICALLY VARYING RESIDUAL MECHANICAL STRESSES DURING DIAGNOSTIC OF STRESSED CONDITION OF MONOCRYSTALS BY MEANS OF ULTRASONIC ECHOPULSE METHOD
The paper covers theoretical analysis of influence of harmonically varying residual mechanical stresses on series of ultrasonic pulse multiple reverberations in monocrystal plane-parallel sample. The paper also deals with features of ultrasonic wave propagation in half-infinite environment with harmonically varying mechanical stresses. Author suggests an ultrasonic echo-pulse method of identification of homogeneous stressed condition with minimum residual mechanical stresses.
