Abstract

In this paper moisture effects on damage processes are studied experimentally and numerically. In the experimental part the coupling between mechanical and hygric loading during three point bending is investigated using microfocus X-ray projection. This method allows visualizing and quantifying the transport of liquid water in the porous material and the cracks. In the modeling part, two recently developed discrete models, one for simulating discrete damage processes and a second for simulating fluid transport through cracks, are combined in a poromechanical framework.
