Given the importance of injection molding as a process as well as the simulation industry that supports it, there was a need for a book that deals solely with the modeling and simulation of injection molding. This book meets that need. The modeling and simulation details of filling, packing, residual stress, shrinkage, and warpage of amorphous, semi-crystalline, and fiber-filled materials are described. This book is essential for simulation software users, as well as for graduate students and researchers who are interested in enhancing simulation. And for the specialist, numerous appendices provide detailed information on the topics discussed in the chapters.

Kennedy, P.

Peter Kennedy, a native of Melbourne, Australia, studied Mathematics and Education at Melbourne and La Trobe Universities and has a Doctorate in Mechanical Engineering from the Technical University of Eindhoven. After teaching high school mathematics, Kennedy joined Moldflow, the first commercial company to provide simulation software for injection molding. During his 22+ years at Moldflow, Kennedy worked in various positions related to molding simulation and the development of the company's key technologies through internally directed research programs and cooperative projects with academic and industrial research organizations.

Zheng, R.

Rong Zheng was an Australian citizen, who was born in Xiamen, China. He obtained a BSc in Mechanical Engineering in 1982 and a Master degree in Polymer Processing in 1985 at South China University of Technology and a PhD in Computational Rheology in 1991 at the University of Sydney. From 1993 to 2009, Zheng worked for Moldflow Pty. Ltd. (now Autodesk) on research and development of science-based technology for modeling and simulation of injection molding. He was also involved as a Chief/Partner Investigator in several collaborative research projects between Moldflow and universities. Most recently, he was an Adjunct Associate Professor of Mechanical Engineering at the University of Sydney. He passed away on January 6, 2014.
