On the decay of the energy for radial solutions in Moore-Gibson-Thompson thermoelasticity. (English) Zbl 07589901

Summary: In this paper, we consider the Moore-Gibson-Thompson thermoelastic theory. We restrict our attention to radially symmetric solutions and we prove the exponential decay with respect to the time variable. We demonstrate this fact with the help of energy arguments. Later, we give some numerical simulations to illustrate this behaviour.
