“A new physical aspect for elastic-viscous transition and velocity jump in fracture of rubbers”

This figure shows the frequency f of vibration generated during tear fracture of rubber against the crack growth rate G˙ over three different fracture zones, where in the transitionⅡ f increases proportionally withG˙, meaning that the vibration energy converted from the external strain energy works as a driving force for the accelerated crack propagation, thus causes the velocity jump in the transition zoneⅡ.97
