摘要:

In this work, geometrically nonlinear transient response of laminated plates with nonlinear viscoelastic restraints is investigated by a numerical method, in the computational platform-MSC.Nastran. The variable constraining forces as functions of dynamic displacements and velocities are added to the right-hand side of equation of motion as additional applied loads. These loads are represented by an independent set of functions that satisfy the various constraint conditions for specific cases. The nonlinear equations are solved by using the load increments scheme in conjunction with Newton-Raphson iteration. The time history of transverse displacement at a typical point is given through a series of transient analysis. Then the comparisons of the responses for different parameters of the Kelvin-Voigt model and boundary conditions are made. The numerical results show that the present method is validated to be effective for treating geometrically nonlinear transient problems with nonlinear viscoelastic restraints.
