| contents | We present a novel experimental approach based on 3D printing and X-ray computed tomography to characterize fracture aperture distribution and evolution in 3D fracture networks under varying stress loading conditions. We validate our methodology by comparing experimentally measured stress-dependent fracture apertures with both analytical solutions and numerical simulations, for both single fracture and fracture network scenarios. We show that, for fracture deformation under linear elastic regime, our experimental results agree with numerical simulation. Furthermore, by combining our new experimental methodology with advanced numerical simulations, we illuminate the complex interplay of stress and topology in fracture network deformation. Our approach opens the door for experimentally observing deformable fracture networks under stress in 3D space, which has significant implications for understanding and predicting many geophysical problems involving fractured geological media. |
