SUMMARY
Small scale yielding refers to a concept in fracture mechanics where non-linear effects, such as crack tip plasticity, blunting, and micro defects, are confined within a zone that is characterized by linear elastic behavior. This phenomenon occurs at the crack tip, allowing for a clearer understanding of stress distribution and material failure. The term is crucial for analyzing the mechanical behavior of materials under stress, particularly in the context of structural integrity and failure analysis.
