Abstract
Plates with variable thickness are widely used because of their high strength and durability. An effect of circular variation in thickness along with linear variation in density on thermal-induced vibration is studied. The geometry of the plate is considered to be rectangular. The thickness, as well as density variation of the plate, is to be taken one dimensional. For thermal effect, the temperature of plate is to be taken bi-parabolic. To solve the governing differential equation, Rayleigh–Ritz technique is applied for different value of nonhomogeneity, thermal gradient, tapering parameter, and aspect ratio. Results are calculated for Duralium material with high-level computational software MAPLE and presented with the help of graphs.
