LASER-ULTRASONIC DIAGNOSTICS OF RESIDUAL STRESS IN THIN-WALLED ELEMENTS OF SPACE-ROCKET TECHNIQUE

Annotation

  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.
