On the asymmetric dynamic response of viscoelastic sector plate made of FG polymer foam

This work provides an analytical investigation of the damped forced vibration behavior of viscoelastic annular sector plates made of porous polymer foam. For this aim, the motion equations are obtained through first-order shear deformation theory (FSDT) in conjunction with the energy method and the...

description This work provides an analytical investigation of the damped forced vibration behavior of viscoelastic annular sector plates made of porous polymer foam.

The perturbation technique and Fourier series are employed to solve the system of equations with variable coefficients. The equations with variable coefficients are changed to a system with constant coefficients by inserting a new variable, and the asymmetrically dynamic response is computed analytically in a closed-form solution.
