Opis

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.

For mechanical engineers, polymer engineers, and applied mathematicians who want to increase their understanding of flow analysis technology, this book is a thorough introduction to the theoretical background of computer simulation of the injection molding process, including MOLDFLOW. §Contents: Material Properties for Flow Analysis. Governing Equations of Fluid Flow. Mathematical Models for Injection Molding. Finite Element Formulation of the Mathematical Models. Numerical Solution of the Models.

He 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 Peter joined Moldflow, the first commercial company to provide simulation software for injection molding. During a total time of 22 years at Moldflow he 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. Rong Zheng is an Australian citizen and was born in Xiamen, China, in 1947. 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, where he continued as a Post-doctoral Fellow from 1991-1993. From 1993 to 2009, he was working in Moldflow Pty. Ltd. (now Autodesk) on research and development of science-based technology for modeling and simulation of injection molding, and was involved as a Chief/Partner Investigator in several collaborative research projects between Moldflow and Universities. He is currently an Adjunct Associate Professor of Mechanical Engineering at the University of Sydney.
