Abstract
Effect ofthermal gradient on the naturalfrequency, buckling load and dynamic stability ofa simply supported tapered beam under a pulsating axial load is investigaled by Jinite element method. A linear variation of the Young's modulus of the beam material, due to a sleady one-dimensional thermal gradient is assumed. It is observed that the naturalfrequency and the buckling load ofthe beam decrease with increase in thermal gradient and thermal gradient has a destabilizing effect on the beam
