Abstract

This paper is concerned with the damping of elastic beams of two different kinds. The first model involves the application of viscous damping at a single point either in the interior or at the boundary. The second involves a thermoelastic beam model in which mechanical damping is applied at a boundary. Since the second model is known to be uniformly stabilized via thermal effects alone, an analysis of the relative importance of the thermal and applied mechanical damping is presented. A careful analysis of the effects of rotational forces is also included using realistic model parameters. © 2010 Elsevier Ltd. All rights reserved.
