4.6 Conclusions University of Strathclyde

Finite Element approaches for analyzing nett-forming by Injection Forging are described with reference
to modeling strategies, procedures, and applications; employment of Finite Element Modeling as an
analysis engine to develop a design/analysis system for component/tool design for Injection Forging is
also described with reference to design methodology, the structure of design-support, and software
development considerations.
