dc.descriptionReported is an original and innovative method for the stress determination based on an analytical function of the process parameters for the backward extrusion process. Awarded the 2001 Thomas Stephen Prize by the Institution of Mechanical Engineers.
dc.description.abstractThe economics of forging requires tools to be designed to ensure maximum service life. Ideally, this should be achieved by determining the maximum equivalent stress experienced by tools during service. However, the determination of the maximum equivalent stress in the dies through numerical simulations is very time consuming. For the case of a backward extrusion process, this paper proposes a method for its determination that is based on an analytical function of the process parameters. This function was obtained by generating a database that includes the maximum equivalent stress for a large range of process parameters. This database was then modelled by a function determined through statistical analysis. (Professional Engineering Publishing)
