ELASTIC-PLASTIC FRACTURE MECHANICS: A CRITICAL REVIEW

The use of fracture mechanics as a tool for structural design and analysis has increased significantly in recent years. Fracture theories provide relationships among fracture toughness, stress, and flaw size and are used, for example, to establish acceptance standards for material defects in structures. This first part of a two-part report reviews the history and current state of the art in elastic-plastic fracture mechanics as applied to welded steel structures. Fundamental concepts and underlying assumptions are described. Standardized test methods and recent developments are reviewed. The results of a parametric study comparing several elastic-plastic design analyses are presented.
