Abstract
The shock loading of a plate made of fragile material is considered. The hypothesis is accepted that destruction of a plate can happen at the expense of a multiple splitting off of its back part because of action of the reflected pulling stresses and a simultaneous cut of a front part in the form of a stopper because of the action of tangential stresses generated by a wave of compression. It is shown that the destruction of a ceramic plate can happen at the expense of a multiple splitting off of its back part because of action of the reflected pulling stresses and a simultaneous cut of a front part in the form of a stopper because of the action of tangential stresses generated by a wave of compression. Necessary and sufficient conditions a punching of a plate are formulated and probable coordinates of its sections in which there are destructions of the type of a splitting off are determined. The results of numerical calculations are presented. The received formulas can help to pick up the characteristics of the striker providing punching of holes of the necessary diameter in plates made of friable material with beforehand given properties.
