Mechanisms of femoral fracture [PDF]

open access: yesJournal of Biomechanics, 1980
Abstract Mechanisms of femoral fracture of the condyles and shaft were experimentally investigated through controlled knee impact of denuded femurs in six human cadavers. High-speed movies recorded knee joint compression, femoral displacements and deformation, and fracture initiation.

Effect of graphitization on mechanical properties of untwisted carbon nanotube yarn and its strength development mechanism

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Carbon nanotube yarn, which is an aggregation of Carbon nanotubes (CNTs), enables CNTs to be used on macro scale. However, tensile strength of the CNT yarn is much lower than CNT itself, and improvement of the mechanical properties is a challenge for ...
