Simulating Metal Forming Processes – Material Characterisation

Simulating Metal Forming Processes – Material Characterisation




Metal forming simulations are increasingly adopted by manufacturers to improve the quality and performance of products and processes while shortening development cycles so that these products can be brought to market earlier. Successful simulation of metal forming processes requires a range of input data about the geometry of the workpiece and tooling, the process forces and tooling motion and, above all, the characteristics of the workpiece material. The accuracy of the results depend on having a good understanding of this input data.


In this presentation, we introduced manufacturing process simulation methods for a range of metal forming operations and then review the material characterisation requirements for processes such as stamping, machining, casting and forging.

About the speakers

Trevor Dutton from Dutton Simulation, but representing the NAFEMS Manufacturing Process Simulation Working Group today.

Trevor graduated in 1986 and joined consulting engineers Arup specializing in non-linear stress analysis chiefly using LS-DYNA in a variety of safety-related applications. Since early 1990s he has focused on process simulation, chiefly sheet metal pressing for automotive, using LS-DYNA and other solvers.

Trevor started Dutton Simulation in 2003 supplying software and consultancy services to metal forming companies mainly in the UK and is currently a member of two NAFEMS Working Groups – Trevor wrote “Why Do Manufacturing Simulation” published by NAFEMS in 2017.

Dr Sumit Hazra completed his PhD in 2001 from Imperial College, for which he was awarded the Alan Glanville prize. Since 2013, he has held the position of Senior Research Fellow in WMG, University of Warwick. He has published 30 articles on modelling, including the fracture of polyethylene and forming of sheet metals with the stamping, bending and roll-forming processes. His latest interests are in the formability of recycled aluminium and the remanufacturing of ultra-high strength steels for the heavy duty and yellow goods vehicle sectors.
