Abstract

In the present study, the effect of thermal gradient on the vibration of different types of triangular plates is discussed. Tapering in triangular plate is assumed bilinear. Variation in temperature of plate material is considered as linear in x-direction. The Rayleigh–Ritz technique is employed to evaluate the first two modes of frequency parameter for different values of thermal gradient, taper parameters and aspect ratios. The author reported frequency for both the modes of vibration for different types of clamped triangular plates, i.e., an isosceles triangular plate, right-angled isosceles triangular plate and scalene triangular plate. All numerical results are presented in tabular form.
