Estimation of the stressed-strained zone after the explosive load by the holographic interferometry

The paper presents the methods and results of the estimation of dimensions of the effective plastic zone in a steel plate after the contact explosion of a detonating cord with the use of the holographic interferometry. A shap e and dimensions of the residual stressed-strained zone are determined by t he control of the orientation and interference band frequency in the interf erograms of the object studied. The data on hardness and structure in the p late studied are presented.
