Summary on Grant Application Form
The objective of this programme is to develop a computational procedure and software tools for the modelling of forming processes, so as to facilitate near net shape product manufacture in the context of precision forming. The approach uses a novel suite of algorithms based upon FV-UM methods that have been integrated into a single software framework that facilitates closely coupled interactions between fluids and structures. A procedure orignially designed for dynamic fluid structure interaction (DFSI) in modelling flow induced vibrations, will be exploited to ensure the physical coupling between the work-piece and the die is adequately represented. The overall approach is based upon the use of a free surface non-Newtonian flow field in a fixed sub-domain mesh to represent the work-piece, and conventional Lagrangian elasto-vosco-plastic solid mechanics analysis for the die. Friction and thermal effects are also accounted for in the formulation. This approach avoids the need for contact analysis and re-meshing. The DFSI procedure provides for full coupling between the work-piece and the deforming die, which provides the potential to design the die system to produce the desired component geometries to very close tolerances, and heralds the way to near net forming. The whole model will be implemented within the PHYSICA multi-physics framework which is inherently parallel; this will facilitate the generation of simulation results within practical timescales for use in the design process.
