摘      要：Polymer chain coils with entanglement is a crucial scale of structures in polymer materials since their relaxation times are matching practical processing *** on the phenomenological model of polymer chain coils and a new finite element approach,we have designed a computer software including solver,pre-and post-processing modules,and developed a digital analysis technology for the morphology of polymer chain coils in flow fields(DAMPC).Using this technology we may simulate the morphology development of chain coils in various flow fields,such as simple shear flow,elongational flow, and any complex flow at transient or steady *** applications made up to now show that the software predictions are comparable with experimental results.
