Project Rock properties during debonding
From CT-scans, investigation of the impact of the debonding on the elastic properties (Young, bulk and shear) of a cemented granular medium.
The microstructure evolution is solved with a Phase-Field formulation, while the mechanical homogeneization is solved with a Fast-Fourier Transform.
The CT-scans employed are from [1, 2].
