Abstract
This paper describes simulation studies using the public domain version of the DYNA3D hydrocode of the torsion test, which by definition is a 3 dimensional test. The mesh resolution required to resolve the stress system and the general shear deformation within the gauge length of the specimen has been investigated. Furthermore the simulations have been compared in detail with experiments in terms of the shear stress/strain curve and the general strain distribution over the gauge length under conditions of steady deformation for iron and RHA. Once the numerical technique has been proven then aspects of localisation and instability can be more thoroughly investigated under a well characterised loading scenario.
