DOI: 10.1002/srin.202000227
Abstract: Around 69% of the worldwide steel production is still based on pig iron production through the blast furnace (BF) route. Although the overall process and the chemical reactions inside a BF are well understood, it… read more here.

DOI: 10.1007/s10035-021-01141-2
Abstract: We investigate how force chains in a granular packing influence and change during a tunnel excavation process. A two-dimensional (2D) frictional cohensionless packing is considered under gravity and a set of contiguous particles are removed… read more here.

DOI: 10.1103/physreve.105.l022901
Abstract: In this letter, we present evidence for a mechanism responsible for the nonclassical nonlinear dynamics observed in many cemented granular materials that are generally classified as mesoscopic nonlinear elastic materials. We demonstrate numerically that force… read more here.
