Although the transition velocity c varies with crosshead speed (and also with spring stiffness), a plot of loading rate vs. c gives a straight line on which points from different [Pg.353]

FIGURE 17. Comprehensive peel data for a natural-rubber-based surgical adhesive peeling from glass. Sigmoidal curves show soft-machine data at different crosshead speeds while error bars show hard-machine (vertical) and dead-load (horizontal) data. Only soft-machine tests reveal the lower bound and transition phenomena. [Pg.353]
