Crack coalescence and brittle failure characteristics of open rock bridges

open access: yesYantu gongcheng xuebao, 2020
The coalescence of rock bridge of fractured rock mass with end cracking is the main cause of the sudden damage of the rock mass, and the brittle failure is obvious.

Experimental study on initiation and damage strength characteristics of similar materials of basalt brittle

open access: yesYantu gongcheng xuebao, 2023
The crack initiation and crack damage strengths of rock are the important indexes to evaluate the high stress failure of hard rock. Based on the Hoek triaxial compression tests and acoustic emission tests, a brittle rock-like model material that can ...

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 ...

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

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.

A brittle star-like robot capable of immediately adapting to unexpected physical damage [PDF]

open access: yesRoyal Society Open Science, 2017
A major challenge in robotic design is enabling robots to immediately adapt to unexpected physical damage. However, conventional robots require considerable time (more than several tens of seconds) for adaptation because the process entails high ...

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.

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 ...

Constitutive modeling of damageable brittle and quasi-brittle materials

open access: yesInternational Journal of Solids and Structures, 2017
Abstract The objective of this paper is to develop a constitutive model for damageable brittle and quasi-brittle materials. A damage model, which can handle damage anisotropy, distinct tensile and compressive damage behavior, and damage deactivation simultaneously, is developed.
