Dive into the critical difference between stress concentration factors and Linear Elastic Fracture Mechanics (LEFM) when analyzing sharp cracks in materials!
What You'll Learn:
• Stress Concentration Factor, Kt: We'll review the classical approach using the Inglis solution for an elliptical hole to understand how stress concentrates at geometric discontinuities.
• The Problem with Sharp Cracks: Discover why the Kt approach fails for a perfectly sharp crack tip, leading to the mathematically impossible prediction of infinite stress.
There is a need for a new parameter to deal with sharp cracks in structures.
