During the tests for evaluating shock behavior for certain alloy steels, one of the stages consists of an analysis of geometrical and structural degradations. These degradations are functions of stress distribution, values, and module of plastic and elastic deformation energies involved. High values of kinetic energy generated at shock imposed the necessity for a scientific model of study / simulation. The presented model allows a further extension for ranges of values and restrictions imposed to shock stresses for certain alloy steels special structures. In order to evaluate and calibrate the presented model, some experiments were conducted. Data resulted from experiments was compared to data resulted during simulations. After calibration and confirmation of proposed model, new parameters could be computed, parameters that were unavailable in experimental studies. The present paper presents some considerations regarding the adopted methodology, results, and perspective for further experimental trials and simulations.
