Abstract
When subjected to dynamic loads, the mechanic properties like damage, permeability and strength of cohesive materials such as concrete, rocks or ceramics are greatly influenced by loading rate. Furthermore, quasi-brittle geomaterials exhibit a microcracking more distributed under dynamic loads compared to the one generated by static loads. This article focuses on the influence of dynamic loads on the permeability and damage of cohesive cementitious materials. The practical objective is to develop a technique aimed at inducing a distributed state of microcracking in rocks instead of localized fracture to stimulate the production of tight gas reservoirs, a potential alternative to hydraulic fracturing. The dynamic loads are compressive shock waves generated in water by Pulsed Arc Electrohydraulic Discharges (PAED). The experiments were carried out on small hollow cylinder specimens under different vertical and radial confinements. Shock waves are generated in the centre of the specimen and propagate in water and into the solid. The specimen is damaged by the pressure waves and its permeability increases with the evolution of damage. Here both concrete specimens and rock specimens were tested. X-ray scans and microtomography have been used to analyze the evolution of the microstructure of representative specimens qualitatively. At the meantime, the simulation was carried out by the finite element codes Europlexus and Cast3M. An anisotropic damage model is devised which takes account of the loading rate effect and the crack closure effect. The coupling between the anisotropic damage and permeability has been realised. A good correlation has been observed between the experimental and the numerical results.
