Abstract

See full text

A process and apparatus for providing simulation and modeling and control which permits user feedback for purposes of implementing design and process optimization for composite or powder compact materials. Control is achieved through a dual feedback and feedforward hierarchical control scheme employing an interactive modeling system for providing the feedforward control data and a PID control loop for the feedback control. Modeling is based upon constitutive equations which form the basis of modeling solutions derived from the micromechanical relationships inherent in the consolidated materials. The system is implemented in an FEM software platform such that a graphics based visualization in three dimensional form can be provided to the user.
