Abstract: Based on the nonclassical theory of shells, an energy-consistent resolving system of dynamics equations for cylindrical shells made of metal-plastic is obtained as a result of minimization of the total-energy functional of a shell as a three-dimensional body. The numerical method for solving the formulated initial-boundary-value problem is based on an explicit variational-difference scheme. The validity of the method is confirmed by the results of comparison of numerical solutions and experimental data. The ultimate deformability and strength of homogeneous fiberglass cylindrical shells and double-layer metal-plastic shells are anlyzed for various reinforcing structures.
Keywords: composite materials, cylindrical shells, strength, fracture, numerical methods, explosive loading.
