Stress Intensity Factor, Ki

Unlock the secret to predicting fracture in materials! This video dives deep into the Stress Intensity Factor (Ki) - the single most important parameter in Linear Elastic Fracture Mechanics (LEFM). What You'll Learn: • The Problem Solved: Understand how Ki remains a finite, measurable quantity, overcoming the classic LEFM dilemma where stress approaches infinity at a sharp crack tip. • Mode I Derivation: Follow a step-by-step derivation of the Ki equation for a Mode I (opening mode) center-cracked plate under remote tension. • The Geometry Correction: Learn how the derived factor is modified by the non-dimensional parameter Beta, which accounts for the influence of specimen geometry, crack shape, and loading conditions on the true stress intensity. • The Three Modes of Fracture: Get introduced to the three fundamental modes of crack displacement: o Mode I Ki: Opening (Tensile) o Mode II Kii: Sliding (In-Plane Shear) o Mode III Kiii: Tearing (Anti-Plane Shear)
