Four particular cases are considered depending on the choice of the constitutive tensors, assuming different dissipation mechanisms determined by Moore-Gibson-Thompson-type viscosity. For all of them, the existence and uniqueness of solutions are shown by using semigroup arguments. The energy decay of the solutions is also analyzed for each case.
