Abstract
Newman had brought his crack closure model. It is done well in simple closure model, but it is not exactitude when there is a complex elastic-plastic region in crack front and has a variety stress-ratio. The paper improved the Newman's model. Using the model, the crack growth are calculated on the variety stress-ratio and over-loading. The crack closure is simulated.
