Fracture and Damage

1985
After summarising the theory of damage of Rabotnov-Katchanov and its subsequent developments by Lemaitre and Chaboche, it is pointed out how this concept has been extended to ductile fracture in an overall manner, or by taking into account the physical mechanism of development of cavities. It is found that the rate of damage is proportional to the rate

Coupled thermo-damage and damage-fracture fields

1999
The creep process and the associated material deterioration are temperature sensitive phenomena. A classical approach consists in accounting for the effect of temperature on the material functions in the constitutive and the evolution equations of a damaged solid (cf. Ganczarski and Skrzypek, 1991), whereas the temperature field remains steady state.

Damage and self-similarity in fracture

Theoretical and Applied Fracture Mechanics, 2003
Abstract Consider applications of damage mechanics to material failure. The damage variable introduced in damage mechanics quantifies the deviation of a brittle solid from linear elasticity. An analogy between the metastable behavior of a stressed brittle solid and the metastable behavior of a superheated liquid is established.

Damage Model for Ductile Fracture

1986
Large plastic strain in metals is accompanied by nucleation and growth of microvoids and microcracks. This phenomenon is called “ductile plastic damage”; it leads to plastic (“ductile”) fracture. This kind of fracture is considered, for example, in the book of McClintock and Argon [1], from the viewpoint of physics.

Fracture and Damage of Composite Laminates

1994
Models for prediction of fracture and damage in composite laminates are presented. Present knowledge on the controlling mechanisms of fracture and damage are as well discussed. Failure criteria and failure mechanisms are first presented for unidirectional laminates.

Distributed Damage Processes in Fracture

1987
Fracture events in materials occur in a wide variety of ways, ways which differ in both macroscopic and microscopic characteristics. One class of such characteristics has come to be called “distributed damage”. The concept of distributed damage processes as part of a total fracture event implies multiple sites of cracking, void formation, or other ...
