DOI: 10.1002/nme.5509
Abstract: Summary This paper presents a numerical investigation of microscopic lubricant flows from the cavities to the plateaus of the surface roughness of metal sheets during forming processes. This phenomenon, called micro-plasto-hydrodynamic lubrication, was observed experimentally… read more here.

DOI: 10.1016/j.wear.2021.203733
Abstract: ABSTRACT Metal forming involves relative motion between a tool and a workpiece under very high contact pressures, thus possibly leading to severe tool wear, compromising the process stability and the quality of the final product.… read more here.
