Figure 3.

Strain-induced changes in adhesive fiber properties. (a) Adhesive fibers were strained to 50%, held for 10 minutes, and then strain removed. Images of the sample from the side before straining (left) and after strain removal (right). (b) Representative plot of the experimental tangent modulus (E_t) (light blue circles) from adhesive fibers strained with holding at 50% strain (left) or without holding (right). Plots also include results of E_t determined through a continuum model simulation of these loading conditions (black, diamonds). Scale bar is 15 mm.
