The Relationship

The work described in this paper was carried out in two parts. The first part consisted of evaluating the machining constants and the dynamic shear flow strengths of bovine bone from orthogonal cutting and drilling tests. The second part of the work arose from investigation into the thermal effects of drilling human bone during which certain trends were observed when comparing feed rate and point angle for fixed values of thrust. Some measure of agreement was found between these two independent pieces of work. Bera and Bhattacharrya's analytical equation for the thrust produced when drilling metals has been modified for anisotropic materials such as bone.

We have examined the small strain response of an inverse ferrofluid system, consisting of micron-sized inert particles dispersed in a ferrofluid, which is a magnetisable liquid consisting of single domain magnetite nanoparticles. Under a magnetic field the inert particles will form elongated aggregates in the field direction, analogous to a magnetorheological fluid. It was found that the fluid appeared to have a Bingham fluid-like yield stress when analysed using the flow curve. However careful study of the behavior at very low shear rates revealed an ever decreasing shear stress. In addition, the behavior of conventional magnetorheological fluids at large strains under steady shear flow and constant magnetic field was also studied, and the results compared to particle-level computer simulations.
