FIELD: non-destructive investigating of materials.
SUBSTANCE: method includes determining time delay of the pulses of longitudinal and transverse ultrasonic waves propagating along the longitudinal axis of a bolt and these of the waves at the end of the bolt head. The absolute axial stress is determined from the formula proposed.
EFFECT: enhanced reliability.
