Development of a Fatigue Properties Data Base for Use in Modern Design Methods

The objective of this project is to develop a comprehensive database of strain-life fatigue data for graphitic cast irons. Specifically, the structural grades of gray iron, ductile iron, austempered ductile iron and compacted graphitic iron will be included. Each grade will be evaluated with microstructures corresponding to two cast section sizes for comparison, thus resulting in two materials to be described per grade of iron. The purpose is to provide a database of cast iron fatigue properties that is suitable for modern design techniques. This will enable designers to use modern durability modeling to develop more precise and efficient cast iron components. Cast iron producers will benefit by expanded and newly opened markets while end-users will realize cost savings in both component development and manufacture. Iron foundry expenditures will also benefit from the reduced weight of metal in the lighter more efficient component design.
