On constitutive models of viscoelasticity finite deformation

From a kind of polymer,the paper undertakes the research and exploration about the constitutive models for the viscoelasticity finite deformation,calculates the finite deformation for the polymer materials by using the new constitutive models theoretically,and displays the new methods to study the constitutive theory for the finite deformation of viscoelasticity materials by comparing and analyzing the simulation calculation results and the previous conclusion.
