What is Crack Tip Stress Distribution Analysis about?

The lecture discusses the modes of deformation in materials with cracks, identifying three types: opening (mode 1), sliding (mode 2), and tearing (mode 3). It introduces Linear Elastic Fracture Mechanics (LEFM), emphasizing the negligible plastic deformation at the crack tip and the importance of stress distribution ahead of the crack tip, which was first derived by Westergaard. The lecture aims to evaluate this stress distribution using complex numbers and the airy stress function, providing a foundation f
