Static Analysis of Axisymmetric Thermoelastic Thin Plate with Voids

In this paper,a model of thermoelastic thin plate with voids is established based on the theory of thermoelastic materials with voids.An analytic solution of the axisymmetric problem under static state is presented,and expressions of the deflection and voids are obtained with both fixed and simply supported boundary conditions.Numerical computation is carried out.Effects of voids and temperature on the deflection are considered.Influence of thick-radius ratio of plate and temperature on deflection and the change in volume fraction are investigated.
