Abstract. Applicability of laser-ultrasonic method for estimation of residual stress in thin-walled elements is studied experimentally. The investigation is carried out with the use of a laser-ultrasonic defectoscope and laser acoustooptical converters of longitudinal and superficial Raleigh waves.
Keywords:
reliable functioning, residual stress, laser-ultrasonic diagnostics, thin-wall elements.
