| Viscoelastic analysis of an exponentially graded sandwich plate
A. M. Zenkour*
The Journal of Mechanical Science and Technology, vol. 26, no. 3, pp.889-898, 2012
Abstract : Bending response of an exponentially graded fiber-reinforced viscoelastic (EGFV) sandwich plate is investigated using various plate
theories. The plate consists of viscoelastic material faces and an elastic material core. The effective moduli and Illyushin’s approximation
methods are used to solve the equations governing the bending of simply-support EGFV sandwich plates. Numerical results for deflections
and stresses are presented and some of them are compared. The effects due to aspect ratio, side-to-thickness ratio and constitutive
parameter as well as time parameter are all investigated. Concluding remarks are made
