Three-dimensional analysis of functionally graded plate based on the Haar wavelet method

ABSTRACTA three-dimensional analysis of a simply-supported functionally graded rectangular plate with an arbitrary distribution of material properties is made using a simple and efiective method based on the Haar wavelet. With good features in treating singularities, Haar series solution converges rapidly for arbitrary distributions, especially for the case where the material properties change rapidly in some regions. Through numerical examples the influences of the ratio of material constants on the top and bottom surfaces and difierent material gradient distributions on the structural response of the plate to mechanical stimuli are studied.
