Abstract: Abstract The plastic flow and anisotropy of a low-carbon steel (AISI 1018) across a range of strain-rates is probed using compression experiments. Material models are then calibrated from these results. The strain-rates examined were 10−3… read more here.

Abstract: We tackle the question of how anisotropy in flows subject to background rotation favours structures elongated along the rotation axis, especially in turbulent flows. A new, wave-free mechanism is identified that challenges the current understanding… read more here.

Abstract: Fracture of initially crack-free bodies often occurs due to plastic instabilities known as shear bands. Previous computer simulations advanced a myriad of mechanisms to rationalize shear banding. However, they were restricted to planar geometries. We… read more here.
