FIELD: measuring equipment.
SUBSTANCE: loading the test object is performed, recording the number of the acoustic emission pulses (AE) and their amplitude, determining the diagnostic WAE parameter associated with the danger degree of defects, the time to failure, the tensile strength σ*, the breaking Fp load, and comparing it with the critical value [WAE] to determine the danger degree of the AE pulse source and the operability of the test object. Also, this strength evaluating method allows to evaluate the residual resource Nres.
EFFECT: improving the strength control accuracy of the ring and spherical elements of the welded submersible hull.
