Abstract: | Composite structures on an elastic foundation are being widely used in engineering applications. Bending response of inhomogeneous
viscoelastic plate as a composite structure on a two-parameter (Pasternak’s type) elastic foundation is investigated. The
formulations are based on sinusoidal shear deformation plate theory. Trigonometric terms are used in the present theory for
the displacements in addition to the initial terms of a power series through the thickness. The transverse shear correction
factors are not needed because a correct representation of the transverse shear strain is given. The interaction between the
plate and the foundation is included in the formulation with a two-parameter Pasternak’s model. The effective moduli and Illyushin’s
approximation methods are used to derive the viscoelastic solution. The effects played by foundation stiffness, plate aspect
ratio, and other parameters are presented. |
