Opis

This book reviews the latest developments and applications of modeling and simulation techniques in aluminum shape castings, and the need for improvement of these computational techniques. Specifically, topics include design of both the cast aluminum alloy as well as aluminum casting and gating system; modeling, simulation and optimization of both the casting process and heat treatment; modeling and simulation of both casting defect and microstructure; prediction of mechanical performance and influence of subsequent processing on final performance. Developers and users of computational techniques applied to aluminum shape castings as well as end users of castings will find this book extremely helpful.
