Numerical Simulation of Brittle Damage in Concrete Specimens

Strength of Materials, 2005
A framework for damage mechanics of concrete is applied to simulate the nonlinear elastic deformation behavior of concrete using finite element method (FEM). A rather simple isotropic damage model containing essentially no adjustable parameters is shown to produce results in remarkably good agreement with sample experimental data: the damage law ...

Computational micromechanical modeling of transverse tensile damage behavior in unidirectional glass fiber-reinforced plastic composite plies: Ductile versus brittle fracture mechanics approach

, 2020
A detailed micromechanical finite element analysis methodology is presented to predict the transverse tensile (fiber perpendicular) failure behavior of a unidirectional (UD) glass fiber-reinforced plastic composite ply.

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 ...

An experimental study of mechanical behavior of brittle rock-like specimens with multi-non-persistent joints under uniaxial compression and damage analysis

International journal of damage mechanics, 2019
The mechanical behavior of jointed rock masses significantly affects the stability of rock engineering applications. In this paper, the peak strength, Young's modulus and failure patterns of brittle rock-like specimens with multi-non-persistent joints ...

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 ...
