Statistical theory of ceramic damage and fracture
Engineering Fracture Mechanics, 1993The shortcomings of continuum damage mechanics are discussed. A new universal statistical definition of damage of ceramic materials is given from the viewpoint of stochastic evolution of microcracks. The kinetic equation and the accumulative rule of damage are derived.

Application of Percolation Theory to Rock Damage and Fracture
Key Engineering Materials, 2007Rock is a kind of complex and high-disordered geological material, its damage and fracture process usually shows obvious criticality. In this paper, percolation theory is applied to analyze and describe this critical property. First, we discuss the critical fracture probability of rock through percolation and renormalization analysis, and present the ...

Elasto-plastic damage-theories and elasto-plastic fracturing-theories – a comparison
Computational Materials Science, 1998Abstract In 1979, based on the pioneering work of Dougill (J.W. Dougill, ZAMP 27 (1976) 423–437), Bažant and Kim developed the so-called elasto-plastic-fracturing theory for concrete (Z.P. Bažant, S.-S. Kim, J. Eng. Mech. Div. 105 (3) (1979) 407–428), taking inelastic deformation due to both plastic slip and stiffness degradation into consideration ...

Ductile fracture characterization with an anisotropic continuum damage theory
Engineering Fracture Mechanics, 1988Abstract The paper presents an investigation of characterizing ductile fracture of centre-cracked tension specimen made of thin aluminium alloy based on the theory of an anisotropic continuum damage. The characterization is achieved by predicting the crack initiation of the ductile specimen using the finite element analysis.

An anisotropic theory of continuum damage mechanics for ductile fracture
Engineering Fracture Mechanics, 1987Abstract The development of an anisotropic theory of continuum damage mechanics for ductile fracture is described. A new anisotropic damage evolution equation and a constitutive equation of plasticity are formulated using a damage effect tensor M(D) proposed recently by the authors.

Deformation and fracturing behaviour of discontinuous rock mass and damage mechanics theory
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1988AbstractThe mechanical behaviour of a rock mass is strongly affected by discontinuities such as faults and joints. In this paper, a damage mechanics theory is proposed which deals with some sets of discontinuities distributed in a rock mass, for example, joint systems.

Microscopic statistical theory of damage fracture
Engineering Fracture Mechanics, 1990Abstract The shortcomings of damage mechanics foundation are discussed. The new universal statistical damage concept is defined from stochastic evolution of microcracks (microvoids). The kinetic equation of damage-fracture probability is derived.

Nonequilibrium statistical theory of damage fracture for quasi-brittle materials
Engineering Fracture Mechanics, 1997Abstract A nonequilibrium statistical theory of damage fracture is developed on the foundation of nonequilibrium statistical theory of fracture. The evolution of microcracks is regarded as the elementary process of damage to the material structure. The failure probability of the material due to the evolution of microcracks under the action of applied
