The focus of this study is to determine the thermoelastic behaviour of thick annular disc subjected to ramp heating on the upper face while convective heat exchange boundary conditions are prescribed on the curved surfaces. The heat conduction equation involves the Caputo type nonlocal time fractional derivative of order  . The solution of heat conduction equation is obtained in Laplace transform domain and its inversion is done by utilizing the Gaver–Stehfest approach. For the numerical analysis aluminum material is considered and computed results for the temperature distribution, displacement function and thermal stresses are plotted graphically for weak, normal and strong conductivity.
