hybrid rectangular plates, explosive loads, deformation theory A.A. Ilyushin, the principle of the weakest link.

For hybrid rectangular layered plates from arbitrary sets of isotropic structural materials with a symmetric structure of the arrangement of layers relative to the reporting (neutral) surface, analytical formulas for assessing the permissible residual damage under the action of intense explosive loads are obtained. Contour anchors provide for any combination of rigid or hinge conditions of individual sides of a rectangular contour. The considered model is based on the traditional kinematic hypotheses of Kirchhoff, the deformation theory A.A. Ilyushin, the principle of the weakest link for the materials used and the deformation criterion for pre-fracture for all used phase materials. The most widespread law of time variation of pressure at the front of a blast wave is used.
