AFRC-CATP-1417-Holistic Modelling Methodology for Flow Forming

Flow Forming (FF), and incremental bulk forming in general, is known to have narrow stable process window and hence difficult to shape. Process modelling for it is in its early stages and is complicated by the complex and not very well understood process mechanics. Robust FE models for the process consume too large quantities of data and time with questionable outputs.
Building on the work carried out in AFRC-CATP 218 and 454, this project will aim to collate and classify instabilities observed in earlier trials performed at AFRC, and using models of increasing levels of complexities and model simplification techniques, formulate methods to predict the different instabilities.

The project will focus on intelligent model simplification techniques, robust material model development and some failure prediction capabilities in modelling of Flow Forming
