Effect of 2D thermal gradient on free vibration of orthotropic tapered circular plate
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
Plate construction is found in a wide range of structures, some of which include ships, bridges, aircrafts, storage tanks and steel gates. In some cases the maximum deflection of the plate is equal or larger than the plate thickness, in these cases, the mid- plane stretches and the in plane tensile stresses will be developed within the plate. Circular plate with bidimensional parabolic varying thickness and linear temperature are investigated. Separation of variables method used for the differential equation has been solved for vibration of visco-elastic orthotropic circular plate. Frequency equation is derived by using Rayleigh-Ritz technique with a two term deflection function. Frequencies for first two modes of vibrations are obtained for a circular plate for different values of taper constant and thermal gradient.
