Material Forming Process

This publication covers practical techniques such as injection molding, composites forming, die extrusion, hydro-forming, blowing, forging, machining and cutting, and super plastic forming, as well as a number of other specific processes. In addition, the book includes more theoretical treatments, such as the advection equation in forming processes, damage modelling, inverse modelling dedicated to rheology parameter identification, micro-macro modelling, and no local and gradient models. The diverse materials considered include composites, metals, polymers, and even wood and bones. The chapters have been written by specialists from different scientific disciplines in industry and academia, and their contributions emanate from the proceedings of the 4th International Conference on Material Forming, held in Liège, Belgium in April 2001.
