Automated Finite Element Modeling Procedures for Metal Forming Simulations

Abstract

This project is concerned with the development of finite element procedures for effectively performing metal forming simulations in an automated analysis environment. Due to their ability to efficiently provide results to the required levels of accuracy, the desired formulation should support hp-adaptive analysis techniques. These requirements present a technical challenge due to the inability of standard finite element formulations to satisfy the Babuska-Brezzi conditions for general combinations of displacement (velocity) and pressure interpolations needed for hp-adaptivity in the presence of incompressibility constraints. To address this problem we have investigated stabilized finite element formulations for this class of problem. The second area considered was the development of a geometry-based simulation framework capable of supporting automated hp-adaptive technologies using such element formulations on problems.
