Abstract
The paper concerns the numerical solution of a problem on the forced vibration of a shell system under a blast load. The mathematical model of the transient dynamic process in the given multicomponent system is based on the use of a system of hydrodynamic equations to describe the motion of the detonation products and air and equations from shell theory to determine the stress-strain state of the shell system. The hydrodynamic equations are integrated in moving grids by the method developed by S. K. Godunov. The shell-theory equations are integrated by the integro-interpolation method. The distribution of the loads on the shells, the distribution of the maximum strains along the generatrix of the shell system, and the transformations of the detonation products at characteristic points are presented.
