  • The thermoelastic problem of the bounded axisymmetric structures subjected to transient thermal shock was studied. The thermoelastic model for a thick hollow cylinder was built in the context of the generalized Lord-Shulman theory (L-S theory) for thermoelasticity. The Laplace transform technique and the asymptotic properties of the Bessel functions were introduced to derive the analytical solutions of displacement, temperature and stress, which were induced by a sudden temperature rise. The propagation, reflection and superposition of 2 waves, namely the thermoelastic wave and the thermal wave, respectively, were revealed through these solutions, and the jumps generated in the positions of wavefronts were also obtained clearly.
