IMPACT OF BI-LINEAR TEMPERATURE VARIATION ON THE VIBRATION OF ISOTROPIC VISCO-ELASTIC SQUARE PLATES C-C-C-C WITH CIRCULAR THICKNESS VARIATION

Abstract

The dynamic response of isotropic viscoelastic square plates to temperature variations is a critical area of study in structural mechanics and materials science. This research paper investigates the influence of bi-linear temperature distributions on the vibration characteristics of such plates. Through analytical formulations and numerical simulations, the paper explores how abrupt changes in temperature across the plate's thickness affect its natural frequencies, mode shapes, and damping properties. The findings provide insights into optimizing the design and performance of viscoelastic structures under varying thermal conditions.
