THE NONLINEAR CONSTITUTIVE RELATION OF INCOMPRESSIBLE VISCOELASTIC MATERIALS
对不可压黏弹材料非线性本构关系的探讨

By using the tensor analysis,the paper proves that the three theories for describing the nonlin- ear constitutive relation of incompressible viscoelastical materials,including BKZ theory,Lianis theory and Chirstensen theory,have a same representation when they are used for the uniaxial tension of isotropic ma- terials.And we also show that the three theories amount the same in explaining the nonlinear constitutive relation.
