Exploring the effect of stress-strain behavior of cemented tailings backfill on the stability of inclined sill mat: A numerical study

open access: yesAlexandria Engineering Journal, 2023
This study aims to investigate the impact of the stress–strain behaviour of cemented tailings backfill (CTB) on the stability of sill mat structures used in underhand cut-and-fill mining.

A coupled elastoplastic damage model for brittle rocks

open access: yesFracture and Structural Integrity, 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 ...

Nanoscale removal mechanisms in abrasive machining of brittle solids

open access: yesJin'gangshi yu moliao moju gongcheng, 2022
Brittle solids with dominant covalent-ionic bonding, including single crystals, polycrystals, and optical glass, are core materials for modern microelectronic and optoelectronic devices that are widely used in energy, communication, transportation, and ...

Concentration versus Oscillation Effects in Brittle Damage [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2019
This 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.

Damage and Failure in a Statistical Crack Model

open access: yesApplied Sciences, 2020
In this paper I will take a close look at a statistical crack model (SCM) as is used in engineering computer codes to simulate fracture at high strain rates.

Adaptive and highly accurate numerical treatment for a gradient‐enhanced brittle damage model

open access: yesInternational Journal for Numerical Methods in Engineering, 2020
We present an adaptive numerical treatment for a recently published model for brittle damage with gradient enhancement. We employ adaptive strategies both in time and space, yielding detailed investigations of the convergence behavior: the damage ...

A Preliminary Investigation on the Role of Brittle Fracture in the Kinematics of the 2014 San Leo Landslide

open access: yesGeosciences, 2019
The stability of high rock slopes is largely controlled by the location and orientation of geological features, such as faults, folds, joints, and bedding planes, which can induce structurally controlled slope instability. Under certain conditions, slope

Isotropic brittle damage and unilateral effect [PDF]

open access: yes, 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.

On the Residual Static and Impact Capacity of Shear-Reinforced Concrete Beams Subjected to an Initial Impact

open access: yesApplied Sciences, 2022
Impact loads in previous research showed to induce brittle responses of statically flexure-critical reinforced concrete (RC) beams designed for ductility.

From Brittle to Ductile Fracture in Disordered Materials [PDF]

open access: yes, 2010
We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond
