Paper Abstract

Methodical aspects of estimating plastic deformation zones following contrasting types of loading (static and explosive) are addressed using holographic interferometry. The paper presents sample cases of identification and determination of the shape and dimensions of plastic deformation zones near the geometric stress concentrator at the uniaxial tension of plane samples of constructional materials, as well as the so-called effective plastic trace left after the directed local explosive effect on a steel plate. In the latter case we use the method of determining the site of deformation of the objects with the diffuse reflection. A plastic zone is identified by interferograms and/or according to the distribution of the orders of the interference bands.
