Continuous Damage of Brittle Solids

1987
Some elastic solids fail not through macro — fracture or plastic flow, but rather through growth of micro — defects. Modelling of such processes occurs through theories of continuous damage mechanics. Thermodynamic aspects of one such theory are discussed in this paper, focussing on limitations of admissible processes, energy dissipation in a loading —

Surface damage in brittle materials

2001
It has long been recognized that structural modifications of the surface layers of materials induced by mechanical processing may affect adversely the performance of engineering components in service. Traditionally, the most deleterious changes have manifested themselves as residual stresses that lower the fatigue life or distort the shape of metallic ...

Brittle Damage Mechanics of Rock Mass

2010
In this chapter, special aspects of brittle damage mechanics are considered, related to the various frameworks by which the behavior of a brittle damaged material can be postulated, still considering the damaged medium as a global continuum. The basic framework of CDM is recalled, stressing the concepts of effective stress and the ways of introducing ...

Micromechanics of Damage in Brittle Solids

2003
This chapter deals with microcrack damage models of brittle deformation in rocklike solids under quasi-static loading. Starting with basic mechanisms of microcrack growth under tension and compression, non-linear stress-strain relationships are derived within the thermodynamic framework with microstructural internal variables. Illustrative examples are

Two-dimensional coupled anisotropic creep-brittle damage and elastic-brittle failure problems

1999
In the frame of the classical theory of thin plates (cf. Chap. 9), the effect of shear deformation due to the transverse stress is disregarded, which is equivalent to assuming of the shear modulus is equal to infinity. A more accurate and realitic theory is due to Reissner.

Brittle Fracture and Damage of Brittle Materials and Composites Statistical-Probabilistic Approaches

2016
Flaws are the principal source of fracture in many materials, whether brittle or ductile, whether nearly homogeneous or composite. They are introduced during either fabrication or surface preparation or during exposure to aggressive environments (e. g. oxidation, shocks). The critical flaws act as stress concentrators and initiate cracks that propagate
