摘要：

A dynamic analysis of shear-deformable rhombic plates from functionally graded material (FGM) with a variation in the mass is presented. The present mathematical model incorporates a realistic cubic variation of the thickness coordinate in displacement fields. Due to the parabolic variation of the transverse shear strains in the thickness, the shear-correction factor is eliminated. The finite-element formulation of the present mathematical model is done using a two-dimensional C-0 element with seven nodal unknowns. A computer code is written for the present finite-element formulation. The material properties vary in the thickness direction of the FGM rhombic plate at any point according to the Mori-Tanaka scheme. The accuracy of the formulation is demonstrated by comparing it with suitable examples from the literature. This is the first attempt at a dynamic study of FGM rhombic plates with a variation in the mass and with various volume-fraction indices, thickness ratios and boundary constraints.
