Cross - WLF 粘度モデル
WebApr 6, 2024 · In Polyflow, I can only select Cross model for shear rate dependence and WLF model for temperature dependence individually. The equation for Cross-WLF is different from Cross and WLF individually. My current approach to combine the equations was to assign the following parameters, finally for WLF shear stress dependence … WebThe empirical WLF equation describing shift factor, a T, is: (6.9) where ε 0 =strain at reference temperature, T 0 =reference temperature, t=time, ε=strain at an arbitrary temperature, T=arbitrary temperature and a T =shift factor. For amorphous polymers, the WLF equation applies to temperature range varying from T g to about T g +100°C. car bingo online
