Do slip-weakening laws shapes influence rupture dynamics?

Jean-François Molinari, Roxane Mathilde Suzanne Ferry

To model rupture dynamics, a friction law must be assumed. Commonly used constitutive laws include slip- weakening laws which are characterized by a drop from static to dynamic frictional stress over a critical slip distance. Within this framework, the pre ...
