Dynamic Design of Compound Shell Structures of Revolution Under Nonstationary Loads

A technique for solving dynamic problems of the behavior of compound shell structures (solving the equations of motion subject to appropriate boundary and initial conditions) is developed. The structurally orthotropic model of a three-layer shell structure with a cellular core is used, for which the integral values of the elastic modulus and Poisson’s ratios are determined experimentally. Numerical algorithms are developed, and the corresponding problems of mathematical theory of elasticity are solved. The numerical results are analyzed.
