Why are mammalian tendons so thick
The maximum stresses to which a wide range of mammalian limb tendons could be subjected in life were estimated by considering the relative cross‐sectional areas of each tendon and of the fibres of… Expand
Mechanical properties of various mammalian tendons
Dynamic tensile tests have been performed, using physiologically relevant frequencies and stress ranges, on various tendons from the legs and tails of 10 species of mammal. No consistent differences… Expand
The spring in the arch of the human foot
Large mammals, including humans, save much of the energy needed for running by means of elastic structures in their legs and feet1,2. Kinetic and potential energy removed from the body in the first… Expand

1. The stresses applied during fast locomotion are sufficient to stretch the tendon far into the linear region of the load-extension plot. 2. The tangent modulus in the linear region is about 1.65… Expand

This paper supplies quantitative data on the hind- and forelimb musculature of common chimpanzees (Pan troglodytes) and calculates maximum joint moments of force as a contribution to a better… Expand
Fatigue quality of mammalian tendons.
When excised tendons are subjected to a prolonged load, whether constant or oscillatory, fatigue damage accumulates, leading eventually to rupture. 'Fatigue quality', assessed by the time-to-rupture… Expand
Fatigue rupture of wallaby tail tendons.
Wallaby tail tendons fail after repeated application of stresses much lower than would be needed to break them in a single pull. We show that this a fatigue phenomenon, distinct from the creep… Expand
The mechanical properties of the human heel pad: a paradox resolved.

In vivo and in vitro mechanical testing of the human heel pad gave apparently different properties for this structure: the in vivo stiffness is about six times lower, whereas the percentage of energy… Expand
Creep rupture of wallaby tail tendons.
The tail tendons from wallabies (Macropus rufogriseus) suffer creep rupture at stresses of 10 MPa or above, whereas their yield stress in a dynamic test is about 144 MPa. At stresses between 20 and… Expand
MECHANICAL-PROPERTIES AND FUNCTION OF THE PAW PADS OF SOME MAMMALS
Unpadded paws would suffer large impact forces when they struck the ground, but paws with elastic pads might be set into oscillation, bouncing up and down before settling on the ground at the… Expand
