Damage formation and suppression in rotary ultrasonic machining of hard and brittle materials: A critical review

Ceramics International, 2018
Rotary ultrasonic machining (RUM) combines diamond grinding with small-amplitude tool vibration, to improve machining processes of hard and brittle materials. It has been successfully applied to the machining of a number of brittle materials from optical

A Geometrically Inspired Model for Brittle Damage in Compressible Elastomers

, 2021
Regularized continuum damage models such as those based on an order parameter (phase field) have been extensively used to characterize brittle damage of compressible elastomers.

A thermodynamic damage model for 3D stress-induced mechanical characteristics and brittle–ductile transition of rock

International journal of damage mechanics, 2023
Due to the existence of true three-dimensional high-geostress in deep underground engineering, rock shows different mechanical properties and brittle–ductile behaviours from conventional triaxial stress states, however, the different characteristics of ...

Threshold damage mechanisms in brittle solids and their impact on advanced technologies.

Acta Materialia, 2022
Threshold damage mechanisms in brittle covalent-ionic solids are outlined. Fracture and deformation modes are analyzed in terms of classical contact mechanics.

Damage progression and acoustic emission in brittle failure of granite and sandstone

International Journal of Rock Mechanics And Mining Sciences, 2021
This paper experimentally evaluates and quantitatively compares stress-induced damage progression and acoustic emission (AE) in granite and sandstone based on continuous acousto-optic-mechanical (AOM) observations.

Size effect analysis of quasi-brittle fracture with localizing gradient damage model

International journal of damage mechanics, 2021
The size effect of a quasi-brittle fracture is associated with the size of fracture process zone relative to the structural characteristic length. In numerical simulations using damage models, the nonlocal enhancement is commonly adopted to regularize ...
