Estimating the strength of welded hull elements of a submersible based on the micromechanical model of temporal dependences of acoustic-emission parameters

Acoustic Methods

Abstract

A nondestructive technique for evaluating the strength of hull elements of submersibles is described. The technique is based on the micromechanical model of temporal dependences of the parameters of acoustic emission that is registered under an original novel technique of loading of a cylindrical hull section. The technique is also suitable for assessing the information value of resource-related acoustic-emission diagnostic indicators.
