A criterion for ductile failure in age-hardenable aluminum alloys
Abstract
In the present work, a new constitutive model is proposed to predict failure in age-hardenable aluminum alloys. In this regard, the existing nano-void theory of ductile failure is extended to precipitation hardened aluminum alloys by incorporating the effects of dynamic microstructure evolution due to the formation of deformation and precipitation induced cellular dislocation substructure. As per the nano-void theory, nano-voids form at …
