A Systems-Type Approach to Problems of Fracture
Fracture is a many-sided problem. It encompasses various elements of structure including the microstructure of material, complex loading, and stress and strain concentrations, as well as a competition among elastic response, plasticity, and numerous modes of cracking. These elements are brought together in the form of a systems-type analysis. The approach, which can be adapted for machine calculations, lends organization to the problem, and reveals strengths and weaknesses in our understanding. Finally, three examples of systems-type analyses are outlined to illustrate the kinds of solutions that may become routine in the future.
