A ductile damage model corresponding to the dissipation of ductility of metal

Engineering Fracture Mechanics, 1996
Although some damage models have been proposed for many years, the initiation of ductile macrocracks of metal under complicated stress states can not be appropriately predicted; the reason for this condition is that deformation in fact dissipating ductility of metal is not taken as the starting point of these damage theories.

On finite damage: ductile fracture-damage evolution

Mechanics of Materials, 1985
Abstract 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 ...

Modelling of the damage in ductile steels

Computational Materials Science, 1996
Abstract The nucleation, growth and coalescence of voids result in ductile fracture of materials. The first coalescence of voids defines crack initiation. In order to describe the initiation behaviour of a controlled rolled structural steel FeE 460 quantitatively, experimental investigations and micromechanical modelling were conducted.

Damage Evolution in Ductile Materials

International Journal of Damage Mechanics, 1996
A 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.

A damage model for ductile metals

Nuclear Engineering and Design, 1989
Abstract A physically-based theory of damage for ductile metals is outlined. It rests upon a direct extension of the authors recently proposed viscoplastic model for finite deformations to include the effects of dislocation—void interactions as they manifest themselves in void nucleation, growth, and coalescence.

Modeling of Damage of Ductile Materials

2019
The paper discusses a thermodynamically consistent anisotropic continuum damage model for ductile metals. It takes into account different elastic potential functions to simulate the effect of damage on elastic material behavior. In addition, a yield condition and a flow rule describe plastic behavior whereas a damage criterion and a damage rule ...
