Abstract:

It has recently been suggested that since ductile fracture is often the end-product of void growth and coalescence, an understanding of the plastic behavior of porous metals would be of use in studying ductile fracture. A plasticity theory for porous materials would also be of value in predicting the mechanical properties of sintered powder products. Possible forms for such a theory are discussed, and an approximate theory suggested by Kuhn is further analyzed. A few applications are made to fracture mechanics. Author
