Material Fracture - Understanding Theoretical Fracture Strength and Surface Creation

Learn about the fundamental concepts of material fracture in this 28-minute lecture that explores the creation of two new surfaces during fracture events. Develop a deep understanding of theoretical fracture strength by examining its relationship with elastic modulus, lattice spacing, and surface energy. Starting with basic principles, progress through equilibrium lattice spacing, stress-strain relationships, and sigma max calculations, concluding with practical analysis and key remarks on fracture mechanics.
