000014230 520__ $$2eng$$aThe plastic zone around a mode I moving crack tip in viscoplastic polymers is studied. A dynamic photo-elastic experiment system is constructed to capture images during crack propagation. The plastic zone wake is observed by the optical microscope from the fractured samples. A dynamic plastic zone model considering the viscoplastic effect is established to estimate the plastic zone size. Compared with the rate-independent model, this model modifies the effect which overrates the plastic zone size in the rate-independent model and agrees with experimental results well. A systematic study on the plastic zone is performed according to our model, which shows that the crack velocity has an essential influence on the plastic zone.
