On finite damage: ductile fracture-damage evolution
Mechanics of Materials, 1985Abstract The tensorial entities pertaining to the presence of a damage zone within a representative material sample are obtained from the micro-macro transition of kinematic quantities in finite deformation. It is shown that they reduce to a ‘small-damage’ tensor as the finite deformation measures reduce to their common infinitesimal counterpart ...

Damage Evolution in Ductile Materials
International Journal of Damage Mechanics, 1996A continuum damage evolution model for ductile materials is derived from the principles of incremental complementary energy and thermodynamics. In accordance with this model, the evolution of damage is dependent on the accumulated strain, the stress triaxiality ratio, and the strain hardening exponent of the material.

Ductile Damage Evolution and Strain Path Dependency
AIP Conference Proceedings, 2007Forming limit diagrams are commonly used in sheet metal industry to define the safe forming regions. These diagrams are built to define the necking strains of sheet metals. However, with the rise in the popularity of advance high strength steels, ductile fracture through damage evolution has also emerged as an important parameter in the determination ...

A nonlinear ductile damage growth law
International Journal of Damage Mechanics, 2014One of the commonly used approaches for the prediction of ductile fracture is the continuum damage mechanics model, in which the void density is represented by a continuum variable called damage. For the prediction of fracture, an evolution law for the void growth, called the damage growth law, is needed. As per the continuum thermodynamics framework,

Elastoplastic Damage Models for Ductile Materials
Advanced Science, Engineering and Medicine, 2020The application of the Elasto plastic-damage model is used to describe the ductile fracture model. Few parameters are responsible for ductile damage and its mechanism can be revealed by using Elasto plastic models. An overview of different models is described in this paper.

Damage evolution in ductile materials: from micro- to macro-damage
Computational Mechanics, 1995This research presents a new simulation concept of damage evolution for metallic materials under large displacements and deformations. The complete damage range is subdivided into both the micro-damage and the macro-damage range. The micro-damage phase is described by the Cocks/Ashby void-growth model for isotropic, ductile materials under isothermal ...

Damage work as ductile fracture criterion
International Journal of Fracture, 1994This paper treats the ductile failure initiation in circumferentially-notched tension specimens and explores the local damage model that is able to represent the continuous degradation of the deforming material. With the aid of finite element calculations, the notched specimens have been simulated numerically and the whole strain-stress history for ...
