ELASTIC-PLASTIC DYNAMICS OF RECTANGULAR COMPOSITE PLATES

Abstract

An elastic-plastic dynamic bending problem of the rectangular lengthened layered-fibrous plates is formulated. An original method of numerical integration of the problem stated is developed based on the generalization of Runge−Kutta methods. The particular calculations on determining a limited dynamic state of the isotropic reinforced single-layered and three-layered plates of constant and variable thickness and the adaptability of such structures are performed under loadings of an explosive type.
