Fracture Behavior and Mechanical Characterization of Obsidian: Naturally Occurring Glass download PDF, EPUB, Kindle. Studying the unique mechanics and structural features of volcanic glass will help in distinguishing the micro fracture behavior of obsidian versus artificial glasses and fused quartz. Furthermore, it will also help provide a basis for microstractural design of artificial glass with increased toughness.
