Abstract

Nonlinear viscoelastic models have been studies to elucidate the nonlinear behavior of viscoelastic materials. It is axiomatic that the analytical solutions of these constitutive equations are helpful to investigate various viscoelastic flows. For this reason, studies on calculating the analytical solutions of viscoelastic models have been spotlighted. However, various studies rely on power series approximations and it cannot overcome the inherent limitation of convergence radius. In this study, new approach is suggested to calculate analytical solutions of the Giesekus model. This approach provides systematic way to calculate not only shear stress but also normal stress under large amplitude oscillatory shear (LAOS) flow.
