Automated Finite Element Analysis for Molding Behavior of PET Bottle

Abstract

This paper describes an automated analysis methodology of 3D structures using optimal design system. An automatic finite element mesh generation technique, which is based on fuzzy knowledge processing and computational geometry techniques, is incorporated into the system, together with a commercial FE analysis code, and a commercial solid modeler. Also, with the aid of multilayer neural networks, the present system allows us to obtain automatically a design window in which a number of satisfactory design solutions exist in a multi-dimensional design parameter space. The developed automated FE analysis system is successfully applied to evaluate the molding behavior of PET bottles.
