Dynamic crack propagation with a variational phase-field model: limiting speed, crack branching and velocity-toughening mechanisms

J Bleyer, C Roux-Langlois, JF Molinari - International Journal of Fracture, 2017 - Springer
We address the simulation of dynamic crack propagation in brittle materials using a
regularized phase-field description, which can also be interpreted as a damage-gradient …

Why soft contacts are stickier when breaking than when making them

A Sanner, N Kumar, A Dhinojwala, TDB Jacobs… - Science …, 2024 - science.org
Soft solids are sticky. They attract each other and spontaneously form a large area of
contact. Their force of attraction is higher when separating than when forming contact, a …

Local and global avalanches in a two-dimensional sheared granular medium

J Barés, D Wang, D Wang, T Bertrand, CS O'Hern… - Physical Review E, 2017 - APS
We present the experimental and numerical studies of a two-dimensional sheared
amorphous material composed of bidisperse photoelastic disks. We analyze the statistics of …

Effective toughness of periodic heterogeneous materials: the effect of out-of-plane excursions of cracks

M Lebihain, JB Leblond, L Ponson - Journal of the Mechanics and Physics …, 2020 - Elsevier
A powerful semi-analytical method is developed to investigate the impact of tough inclusions

Asymptotic homogenization for phase field fracture of heterogeneous materials and application to toughening

S Liu, S Hao, Y Shen - Composite Structures, 2024 - Elsevier
We propose an asymptotic homogenization framework to simulate the fracture of
heterogeneous materials. This framework upscales the phase field model for microscale …

Adhesion of heterogeneous thin films II: Adhesive heterogeneity

This paper continues the study of the effective adhesion of thin films on rigid substrates in
the presence of spatial heterogeneities started in **a et al.(2013). In this paper, we focus on …

Quasi-static crack front deformations in cohesive materials

M Lebihain, T Roch, JF Molinari - Journal of the Mechanics and Physics of …, 2022 - Elsevier
When a crack interacts with material heterogeneities, its front distorts and adopts complex
tortuous configurations that are reminiscent of the energy barriers encountered during crack …

Pinning cracks by microstructure design in brittle materials
