Simulation and control of microstructure evolution during hot extrusion of hard aluminium alloys
X Duan,Terry Sheppard +1 more
TL;DR: In this article, some physical models which are based on dislocation density, subgrain size, and misorientation have been integrated into a commercial finite element modeling program simulating extrusion.

The influence of the constitutive equation on the simulation of a hot rolling process
X Duan,Terry Sheppard +1 more
TL;DR: In this article, the differences of three commonly used constitutive equations (the Norton-Hoff law, the hyperbolic sine function and the Hensel and Spittel equation) for hot deformation are compared with respect to changes of temperature, strain and strain rate.

Simulation of substructural strengthening in hot flat rolling
X Duan,Terry Sheppard +1 more
TL;DR: In this paper, the status of modelling the dislocation substructure evolution by FEM is first reviewed and problems and difficulties in the simulation are investigated, and the material strength is computed by adopting different strengthening models.

Shape optimisation using FEA software: a V-shaped anvil as an example
X Duan,Terry Sheppard +1 more
TL;DR: In this paper, a parameter optimisation system for metal forming is developed by combining the general nonlinear finite element analysis software MARC with the improved constrained variable metric strategy, which is an advanced mathematical programming algorithm for general non-linear constrained optimisation problems.

Modelling of static recrystallisation by combining FEM with empirical models
Terry Sheppard,X Duan +1 more
TL;DR: In this paper, a commercial FEM program, FORGE2®, is combined with empirical models to predict the distribution of the volume fraction recrystallised and the recrystonised grain size through the stock thickness after single pass laboratory rolling of aluminium alloy AA5083.
