Abstract :
The paper discusses on the basis of computational energy approach the effect of damping on stability of damped Beck´s column. By making the present computational approach to the damped Beck´s problem, it has been demonstrated that though the internal damping dissipates energy, the damping at the same time help the non-conservative force to do more work on the column. This paper aims at explaining the mechanism of the effect of damping on stability of non-conservative systems.
