摘要: This study investigates several available sandwich beam theories for their suitability of application to one-dimensional plates with functionally graded core. Two equivalent single-layer based on assumed displacements, a higher-order theory, and the Fourier-Galerkin method are compared. The results also compared finite element analysis. core panel is such that density, hence its stiffness, vary through thickness. variation Young's modulus represented by differentiable function in thickness coordinate, but Poisson's ratio kept constant. A very good agreement found among method,
