Advances in elastic-plastic fracture analysis. Final report
This report presents further developments in the evolution of an engineering approach for elastic-plastic fracture analysis. The methodology involved in the approach and basic crack solutions were published earlier as part of the Plastic Fracture Handbook (EPRI document NP-1931). The present work further develops the physical basis for this approach and establishes the foundation for extending it to three-dimensional crack problems. Highlights of the accomplishments include the development of a simple procedure for incorporating thermal and residual stresses in engineering approach fracture analysis procedures, the development of a comprehensive body of elastic and fully plastic solutions for through-wall cracks in pipes, detailed three-dimensional elastic-plastic analyses of typical surface flaws in pressure vessels, and the development of a line-spring model for obtaining elastic and fully plastic solutions for surface cracks in cylinders.
