✦ Synopsis

In this study the general approximate theory developed in Part 1 for dynamic behaviour of thermoelastic cylindrical shells is assessed by applying it to a coupled thermoelastic problem. The problem involves an infinitely long circular cylindrical shell (CCS) subjected radially to convective boundary conditions at its inner and outer surfaces. The time variations of radial and circumferential stresses and temperature predicted by exact and approximate theories are determined and compared. It is found that even the lowest order approximate theory is capable of predicting the essential thermoelastic response characteristics of the CCS. For the integration of exact and approximate equations a numerical algorithm based on the FFT is employed.
