Mechanical Disruption Methods: Grinding

Forces on the sample are two-fold, namely downward pressure accompanied by a tangential shearing force. Grinding causes tearing and ripping of samples, much like shearing, but differs in that there is direct contact between sample and homogenizer.

Force modeling for 2D freeform grinding with infinitesimal ...

2021-10-1 · A universal method of grinding force modeling in arbitrary 2D freeform grinding is proposed, which is based on the infinitesimal approach. The main idea of this method is to discretize the freeform surface into a group of surfaces with very small widths along the profile of the surface cross section, which can be considered as flat surfaces inclined at different angles.
