Abstract
After a review of the literature on the prognosis of ductile fracture, a damage indicator is developed which is based on micromechanical res ults and adapted to experiments. A calibration of this damage indicato r is possible by inspecting in detail a load displacement curve for a long and smooth specimen. Relation to currently published damage indic ators is discussed. The damage indicators can be used to indicate the onset of a local crack in a ductile structure.
