Remove cohesion after slip occurred on the fault?

Dear Pylith developers,

Is it possible to assign a fault constitutive model in Pylith (static or slip-weakening) with variable cohesion: nonzero cohesion before sliding starts (while slip is zero) and zero cohesion after?


PyLith does not have a fault constitutive model that has slip-dependent cohesion. You may be able to generate something with similar behavior by adjusting the static and dynamic coefficients of friction in the slip-weakening fault constitutive model.
