Document Summary

Strain stretch to the point of damage or break, the movement, how far it stretches (point of breaking = extensibility); x-axis. Stress putting tension on something, the force put into it (point of breaking = strength); Viscoelasticity mix of solid and fluid characteristics. Resilience the ability of an object to take back its initial shape after being stretched no energy loss (same energy when load and unload, stretch and let go) E. g. hagfish defense, getting away from predatory if imprisoned in jaw; Food capture, locomotion, defense, adhesion, reproduction, barrier locomotion in snails: crystalline composite. E. g. elastin in bv; resilin pads flying and jumping insects: bees, fleas; abductin hinge of bivalve muscles (have adductor muscle which contract to close the shell; abductin allows shell to reopen) The breakage in terms of stress and strain does not depend on size of fibre. Stiffer than rubber so fibre breaks at lower stress. Once one bond breaks they all do.
