Isotropic brittle damage and unilateral effect [PDF]

open access: yesComptes Rendus. Mécanique, 2010
This Note investigates the isotropic version of a general macroscopic model for brittle damage accounting for unilateral effects proposed by Welemane and Cormery (H. Welemane, F.

Graded damage in quasi‐brittle solids [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2022
AbstractA novel approach to damage modeling for quasi‐brittle solids is presented relying upon a differential inclusion that is closely related to the one of implicit gradient models. The proposed formulation naturally fits in the so‐called nonlocal standard approach, whereby the framework of generalized standard materials is extended to include ...

Application of damage mechanics in percussive drilling modelling [PDF]

open access: yes, 2005
A stationary-periodic quasi-static model of rock percussive deep drilling is introduced. First, an auxiliary problem of stationary indentation of a rigid indentor is considered.

Studies into the Failure Prediction of Brittle Materials [PDF]

open access: yes, 1987
This thesis is divided into six chapters. The first chapter provides a brief introduction concerning the behaviour of brittle materials. It also contains the justification for the undertaking of the study as well as a brief description of the method ...

Description of Brittle Damage in Concrete [PDF]

open access: yesCommunications - Scientific letters of the University of Zilina, 2002
A simple model of the brittle damage evolution in concrete is presented. The damage evolution is assumed as an isotropic one and the level of damages in material is described by the scalar parameter. The physical equations for this case are formulated.

Study Of The Damage-Induced Anisotropy Of Quasi-Brittle Materials Using The Component Assembling Model

open access: yes, 2008
Damage-induced anisotropy of quasi-brittle materials is investigated using component assembling model in this study. Damage-induced anisotropy is one significant character of quasi-brittle materials coupled with nonlinearity and strain softening ...

A coupled elastoplastic damage model for brittle rocks: elastoplastic damage model for brittle rocks

open access: yesFrattura ed Integrità Strutturale, 2020
Brittle rock contains an important plastic deformation, which causes microcracks when coupled with stress-induced damage. A new coupled elastoplastic damage model is established in order to discuss the damage behaviors found in brittle rock, based on theoretical analysis and experiments.

Concentration versus Oscillation Effects in Brittle Damage [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2020
AbstractThis work is concerned with an asymptotic analysis, in the sense of Γ‐convergence, of a sequence of variational models of brittle damage in the context of linearized elasticity. The study is performed as the damaged zone concentrates into a set of zero volume and, at the same time and to the same order ε, the stiffness of the damaged material ...

Rain erosion damage in brittle materials

open access: yesEngineering Fracture Mechanics, 1983
Abstract In order to understand the processes involved in the high-velocity rain erosion of brittle materials the impact damage produced in soda-lime-silica glass by single and multiple jet impact was studied. The damage was quantified by measuring the post-impact strength of specimens.
