A study on vibration of tapered rectangular plate under non-uniform temperature field

摘要

The present analysis is about to study the vibra-tion of tapered rectangular plate made up of visco-elastic non homogeneous material. Tapering in the plate is con-sidered in one direction. Exponential variation in poisson ratio is assumed for non homogeneous nature of plate’s material. Non uniformity in temperature field is considered bi-linear i.e. linear in x– direction and linear in y– direc?tion. Frequency and deflection for first two modes of vibration are calculated and tabulated for various values of plate parameters. A comparison of the results of present study with those available in literature is given.
