Abstract: The paper describes a simple identification procedure that can be used to construct a function relating the increased diffusivity or permeability to the current mechanical state of the material, based on an experimentally determined relation between the excess flux along the crack and the crack opening.The underlying mechanical model belongs to the class of phase-field formulations (or variational damage models) for quasibrittle materials, but the procedure would be applicable to other types of regularized failure models as well.
