# Nonlinear Vibration of Circular Sandwich Plate Under the Uniformed Load

• Rev Recd Date: 1999-09-22
• Publish Date: 2000-02-15
• The differential equations of the axisymmetric large amplitude free vibration for circular sandwich plates under static load are derived,and a set of nonlinearly coupled algebraic and differential eigenvalue equations of the problem are formulated following an assumed time mode approach suggested.The analytic solutions are presented and a relation for amplitude frequency-load of the plates with edge clamped is derived by modified iteration method.The effects of static load on vibrations of plates are investigated.
