Abstract

Ductile damage in metallic materials is caused by the nucleation, growth and coalesce of voids and microcracks in the metal matrix when it is subjected to plastic strain. The measurement of this damage when progressive strain is applied supposes a challenge, since damage is an internal feature of the material which is not easily measurable as stress or strain are. The different experimental techniques developed over the years for this purpose are reviewed in this work, and the results obtained with some of them are used to calibrate ductile damage accumulation models.
