Mathematic models of nonlinear dynamics problems of viscoelastic orthotropic plates and shells of variable thickness

Abstract

The authors develop mathematic models and effective computing algorithms for solving of nonlinear dynamic problems about oscillations and stability of orthotropic viscoelastic systems with variable rigidity. Geometric nonlinearity and possible development of creep strain (viscous elasticity) are taken into account jointly.
