Abstract
WHEN a metal is strained, the work done is partly stored up as strain energy and partly used up by internal absorption. The ratio () of the energy absorbed to the energy stored is a constant, characteristic of the material, but sensitive to changes in structure and temperature. It is often assumed that the absorption can be represented by a damping force proportional to the velocity of deformation, but such an assumption is not in agreement with the experimental facts.1
