Advanced Casting Optimization

The casting design and development process is reviewed, with emphasis on the use of casting process modeling, finite element analysis, and fatigue life prediction for design optimization. Case studies are described. Various casting alloys, processes, and rapid prototyping technologies available and their selection criterion are discussed. Recent advancements in the the cast alloy design properties as a function of the process and section thickness are presented, along with the strain life fatigue database availability for various cast iron alloys.
