Abstract
In this paper three-dimensional elastic deformation of rectangular sandwich panels with graded core subjected to transverse loading is investigated using a recently developed three-dimensional elasticity solution which has been extended to produce a piecewise exponential model. This model can be applied to any functionally graded plate or sandwich panel with graded core as long as the through thickness stiffness variation can be described by a smooth function. The new approach is fully validated through both comparison with results from the literature and a three-dimensional finite element method which employs user-implemented graded finite elements. As an example the new approach is applied to analysis of sandwich panels with power law variation in stiffness properties of the core and a study is carried out to examine the effect of varying the power law index on panel's response.
