    Abstract

    Transparent rock-like materials have been used as a replica of natural rock to study the crack propagation mechanisms. Previous research focused on materials such as glass or transparent polymethyl methacrylate. In this paper, an alternative transparent material that is manufactured with fused quartz was presented, along with the manufacturing process and deformation behavior during a uniaxial compression test. Three digital cameras were arranged around the specimen during the uniaxial compression test to capture the cracks of the same moment from different angles for 3D reconstruction of the cracks. Results show that fused quartz has a similar deformation behavior as natural brittle rock and has potential for the reconstruction of 3D cracks in rocks for quantitative analysis of crack propagation.
