The ability to numerically simulate the effects of different loading conditions on the strength adaptation of a bone can be a valuable tool in understanding the relationship between the strength of a bone and its mechanical environment. Because signi

A cryogenic ball-milling process to produce polymer/CNT nanocomposites was investigated. Linear low density polyethylene was used as the matrix material and 1 wt % of multiwalled carbon nanotubes (MWCNT) was used as reinforcement. The influence of th

The study of the stress distributions within a bone can provide significant insight into its function and the adaptations that may take place under a set of loading conditions. Because the individual muscle forces acting on a bone are directly relate

Composites of polyethylene oxide and carbon nanotubes were produced by first deagglomerating highly agglomerated multi-walled carbon nanotubes in water, using a high-intensity ultrasonic probe, and then mixing with a solution of the polymer using a h
