Data for Laboratory acousto-mechanical study into moisture-induced degradation of fracture stiffness in granite
(2022)Experimental and theoretical studies have been performed to infer changes in a fracture's stiffness using properties of the transmitted elastic waves for dry and saturated conditions. However, little attention has been paid to how progressive wetting of the fracture affects the transmitted energy and moisture-dependent fracture stiffness. Here, we study the time-lapse acousto-mechanical responses on a free-standing fractured specimen of ...Dataset -
Digital image correlation analysis (crack wetting test)
(2023)In order to evaluate the effect of moisture on the deformation of an individual macroscopic fracture within an unsaturated granite, we used the digital image correlation (DIC) method to measure strains across an induced tensile fracture in a Herrnholz granite prism (63 × 90 × 33 mm, width: height: thickness) undergoing unidirectional capillary-driven water imbibition in two orientations (from the crack tip, and the crack mouth). The DIC ...Dataset -
