Summary
During inelastic deformation the mechanical properties of metals can change considerably. Examples of such changes are given. It is argued that these changes are not necessarily a reliable indicator of damage. Residual strength or residual lifetime are proposed as alternate relative measures. For the case of residual lifetime a method of assessing damage is proposed. This method yields the Palmgren-Miner rule as a special case.
