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