摘要：

Problems of forced vibrations of ellipsoidal sandwich shells under a nonstationary distributed load are considered. When developing a mathematical model of sandwich shells, the theory of kinematic and static hypotheses was used for a laminated ellipsoidal shell. The geometrically nonlinear Tymoshenko shell theory of the second order is applied. A numerical algorithm based on an integro-interpolation method of development of difference schemes in spatial coordinates and an explicit finite-difference scheme in time is used to solve the problems. Numerical results of solving the dynamic problem are given.
