| Abstract: | The relationship between the extensional viscosity and material parameters is studied through the analytical formulas of stress and extensional viscosity derived from the constitutive equation,boundary conditions and the equation of motion of co-rotational Oldroyd fluid B model.By using software MATLAB,the differential equations are solved and the curves of extensional viscosity with other parameters are drawn,and the influence of these parameters on the rheologic behavior is shown.These results qualitatively agree with the experimental results. |
