Deformation and fracturing behaviour of discontinuous rock mass and damage mechanics theory

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1988
AbstractThe 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.

Coupling analysis of seepage and stress in jointed rock mass based on damage and fracture mechanics theory

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
Under the action of remote stress and crack hydraulic pressure, the damage and rupture of jointed rock mass accumulate and develop simultaneously during the process of its crack occurrence and growth. The damage will be accumulated owing to the rupture. The damage is closely related to the rupture. Taking into account comprehensive the stress intensity

Moving from theory to application: Evaluating the numerical implementation of void shape effects and damage delocalization in the modeling of ductile fracture in porous plastic metals

Mathematics and Mechanics of Solids
In this paper, we present a robust exploration of the Gologanu–Leblond–Devaux (GLD) model, an advanced iteration of the Gurson model, designed to predict ductile fractures in porous metals. Going beyond the limits of the original Gurson model, the GLD model accounts for cavity shape effects and non-local strain localization, marking a significant leap

Statistical theory of ceramic damage and fracture

Engineering Fracture Mechanics, 1993
The 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.

Numerical Analysis of Fracture Characteristics of Elliptic Porous Sandstone and its Filling Gypsum Based on Statistical Damage Theory

Geotechnical and Geological Engineering, 2020
In view of the fact that less attention has been paid to the failure characteristics of rock mass structures with different elliptical shapes, based on the statistical damage theory, the finite element calculation model of sandstone with elliptical holes and its filled gypsum is established, the meso-parameters are calibrated by laboratory test results,
