Paper Abstract

Holographic interferometry applied to non destructive testing is a powerful method, usable with any structure (here, pressure spherical reservoirs) provided that it can be acted upon, mechanically or thermically, so as to present two different dimension conditions corresponding to the two superimposed holograms. By revealing the shape of the plastic zone, in the case of a breaking strength test piece acted on by a tractive effort, the method allows to validate a numerical simulation, the results of which are then introduced into a program for calculating the Rice integral, used as a criterion of the breaking point for elasto-plastic materials subjected to a plane stress.
