Damage and fracture: Crystal plasticity models

Physical Mesomechanics, 2017
This paper completes the review of recent (last 15 years) publications on experimental and theoretical methods and approaches for studying damage accumulation and fracture in crystalline solids. It summarizes the works that describe damage and fracture using an approach based on crystal plasticity.

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.

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

Damage and Fracture

2017
Micromechanical aspects, mechanisms and models of fracture are addressed, which have become increasingly topical since the 1990s though the basic ideas and perceptions date back to the early years of fracture mechanics. The characteristics of brittle and ductile damage on the micro-scale and the respective fractographic appearance are outlined and the ...

Time Dependent Fracture and Damage

SAE Technical Paper Series, 1988
<div class="htmlview paragraph">Time-dependent fracture is considered. The damage distribution ahead of crack tip is analysed. The range of applicability of the characterizing parameter for the creep crack growth is discussed on the basis of fracture mechanics and continuum damage mechanics. The creep crack growth rate is determined under certain

Stochastic fatigue, fracture and damage analysis

Structural Safety, 1986
Abstract This paper reviews and summarizes the development and recent progress of methods of stochastic fatigue, fracture and damage analysis. Topics covered include structural fatigue, structural fracture, cumulative damage, maintainability and inspection and structural damage.

Statistics Toolbox for Damage and Fracture

2000
We review a number of statistical models dealing with damage and fracture of heterogeneous materials. A choice is made to emphasize the models which provide tools and concept of relevance to the field, rather than proposing a single model.

High temperature intergranular damage and fracture

Materials Science and Engineering: A, 1997
The estimation of the degree of intergranular damage based on the quantitative metallography of cavitation should be the starting point of any remanent life assessment route. Unfortunately, only limited quantitative measurements are available to provide information on the extent of cavitation in the fracture state in various materials and under ...
