Phase-field modeling of anisotropic brittle fracture including several damage mechanisms

open access: yesComputer Methods in Applied Mechanics and Engineering, 2018
The present paper aims at modeling complex fracture phenomena where different damaging mechanisms are involved. For this purpose, the standard one-variable phase-field/gradient damage model, able to regularize Griffith’s isotropic brittle fracture ...

Energy dissipation and damage evolution for dynamic fracture of marble subjected to freeze-thaw and multiple level compressive fatigue loading

open access: yesInternational Journal of Fatigue, 2021
For rock engineering in cold regions, rock is often subjected to coupled fatigue conditions of freeze-thaw (F-T) and stress disturbance. Rock fracture evolution and energy mechanism under room temperature and constant stress amplitude loading condition ...

Surface fracture behavior and subsurface damage of polycrystalline yttrium aluminum garnet ceramics in Vickers indentation

open access: yesJournal of Materials Research and Technology, 2023
In this paper, the Vickers indentation experiments were carried out under different loads on the polished surface of polycrystalline yttrium aluminum garnet (YAG) ceramics to investigate the surface fracture behavior and subsurface damage under quasi ...

Fracture Damage Characteristics of Rock Under Pre-Peak and Post-Peak Cyclic Loading Condition

open access: yesShanghai Jiaotong Daxue xuebao, 2022
In the process of rock excavation, cyclic loading may occur before or after the peak value. In order to obtain the fracture damage evolution characteristics of rock under the pre-peak and the post-peak cyclic loading condition, the fracture tests of ...

A Synthesis of Fracture, Friction and Damage Processes in Earthquake Rupture Zones

open access: yesPure and Applied Geophysics, 2022
We review properties and processes of earthquake rupture zones based on field studies, laboratory observations, theoretical models and simulations, with the goal of assessing the possible dominance of different processes in different parts of the rupture

A 3D peridynamic fluid–solid coupling damage model of hydraulic fracture propagation

open access: yesEnergy Science & Engineering, 2023
Peridynamics provides a new model and method for describing material failure and fracture development. In this study, a three‐dimensional peridynamic fluid–solid coupling model of hydraulic fracture propagation was established.

Real-Time Early Detection of Crack Propagation Precursors in Delayed Fracture of Soft Elastomers

open access: yesPhysical Review X, 2023
The fracture of materials can take place below the critical failure condition via the slow accumulation of internal damage followed by fast crack propagation.

An anisotropic cohesive fracture model: advantages and limitations of length-scale insensitive phase-field damage models [PDF]

open access: yesEngineering Fracture Mechanics, 2021
The goal of the current work is to explore direction-dependent damage initiation and propagation within an arbitrary anisotropic solid. In particular, we aim at developing anisotropic cohesive phase-field (PF) damage models by extending the idea ...
