A New Analysis Method for Large Amplitude Oscillatory Shear Flow |
| 초록 |
We suggest a new analysis method for large amplitude oscillatory shear flow (LAOS), which is totally different from Fourier transform analysis. The method is based on symmetry of shear stress and the assumption that LAOS in stationary state can be described by a set of bases such as strain and strain rate. Our method decomposes the nonlinear stress data into elastic and viscous parts without depending on any constitutive model. This method is superior to the conventional method such as Fourier anaysis because it contains not only mathematical completion but also rich physical insight. |
