Modelling of dynamic damage and failure in aluminium alloys [PDF]
, 2012 A physically based damage and failure model, applicable to orthotropic metals is proposed in this paper. To account for the physical mechanisms of failure, the concept of thermally activated damage initially proposed by Klepaczko [1], has been adopted as

FE implementation of damage-coupled inelastic constitutive equation for P91 steel
Mechanical Engineering JournalThe objective of this study is to numerically evaluate the cyclic softening behavior and creep-fatigue damage of P91 steel. To achieve this, a damage-coupled inelastic constitutive equation is formulated by coupling the Chaboche-type viscoplastic ...
