Crack bridging and fiber debonding modeling using multiphase continuum and phase-field models Bleyer, Jeremy

Description

In this talk, I will present a particular class of generalized continua called multiphase models which consist of different media possessing their own kinematics and in interaction with each other. This setting is particularly suited to fiber-reinforced media and enables to model in a macroscopic fashion phenomena like bridged cracks or fiber debonding. A variational phase-field combined with a debonding damage law will be proposed for simulating matrix cracks bridged by intact fibers.
