Semi‐crystalline polymers show a complex fracture mechanism, which is controlled by the micro‐mechanisms associated with formation and breakdown of a plastic deformation region. Such regions develop at notches, cracks or other stress‐raising defects. In the present paper, we use time‐resolved synchrotron X‐ray scattering techniques during the deformation process in poly(vinylidene fluoride) to study the plastic zone formation and fracture processes at different strain rates. This gives new insight into the micro‐mechanisms of cavitation, lamellae separation and fibril formation in this particular material.
