Tendon article by Rigby on the mechanical properties of tendon. Tendon exhibits a nonlinear load deformation characteristic.
Tendon article by Rigby in Nature on the mechanical properties of tendon. Tendon exhibits hysteresis in cyclic load-unload protocols and aging effects as well as nonlinearity.
Tendon article by Abrahams on the mechanical properties of tendon. M. Abrahams, "Mechanical behaviour of tendon in vitro", Med. and Biol. Engng. Vol. 5, pp. 433--443.
The mechanical behaviour of horse and human tendon, as characterised by the stress-strain curve, has been examined with respect to load-strain cycling and strain rate. It was found that the tendon stress-strain curve for successive cycles was reproducible provided that strain on the specimen did not exceed 2.0 -4.0 %. If this strain level was exceeded, a permanent deformation occurred. This phenomenon was verified by histological studies on strained tendon which showed that some of the collagen fibres did not return to their original orientation. Variation in the rate of strain was found to affect both the magnitude and the shape of the stress-strain curve. Additionally, it was found that the stress relaxation phenomenon for tendon was essentially the same as that found for other connective tissues.
Gecko toe article by Autumn et al in Nature Adhesive force of a
single gecko foot-hair. Geckos can climb smooth vertical surfaces. Their toes are covered with several hundred thousand fine hairs. This article seeks to understand how the hairs enable the gecko to climb such surfaces.
