Abstract

We examine laboratory data from creep tests performed on a thermally cracked water-saturated glass sample and estimate Young's modulus and extensional-mode attenuation as functions of frequency. An SEM image of a vertical cross-section through the upper half of the cylindrical sample has been digitized and provides key geometric information regarding the crack network. Together with the well-known properties of the glass matrix, this allows for deriving a first-order 2D poroelastic model. Comparing the results of numerical compressibility tests with the corresponding laboratory data indicates that the former are capable of capturing some important characteristics of the latter. This is notably the case for the overall magnitude and frequency dependence of the attenuation and Young's modulus, which corroborates the importance of WIFF in interconnected cracks as the dominant dissipation mechanism.
