Timoshenko beam under the motion of a concentrated point mass resting on a viscoelastic foundation. (a) Timoshenko beam with no stretching effect on simply supported ends resting on a linear viscoelastic foundation, M-1 model, (b) Timoshenko beam with no stretching effect on simply supported ends resting on a nonlinear viscoelastic foundation, M-2 model, and (c) Timoshenko beam with stretching effect on pinned-pinned ends resting on a nonlinear viscoelastic foundation, M-3 model.
