Learn about the fundamental differences between ductile and brittle fracture in this 15-minute educational video that examines both macroscopic appearances and microscopic mechanisms of material cracking. Explore fractography concepts including cup-and-cone fracture patterns in ductile materials and chevron markings in brittle materials. Understand the ductile-to-brittle transition phenomenon through real-world examples, including the historical case study of Liberty Cargo Ships during World War II. Master key concepts in materials science through clear explanations of fracture mechanics, supported by visual demonstrations of how different materials fail under stress.
