ON VIBRATION OF BIDIRECTIONAL TAPERED TRIANGULAR PLATE UNDER THE EFFECT OF THERMAL GRADIENT

摘要

This work deals with natural vibration of isotropic triangular plate under different geometrical and thermal conditions. In this paper, effects of bilinear tapering along with linear thermal condition are discussed for the vibration of triangular plates. Time period and deflection for both the modes of vibration for different types of clamped triangular plates, i.e., an isosceles triangular plate, right-angled triangular plate, and scalene triangular plate, are determined by using Rayleigh--Ritz method. Numerical results are calculated for different values of structural parameters, i.e., thermal gradient, taper parameters, and aspect ratios, and presented in tabular form.
