摘要
Steady shear, oscillatory shear and extensional flow experiments are carried out on the test liquid designated M1. The steady shear experiments cover a shear rate range up to 8 × 104 s-1 and the oscillatory shear experiments involve frequencies up to 40 Hz. Three different extensional flow experiments are involved, namely contraction flow, spinning and the open-syphon technique. A search is made for internal consistency between the various rheometrical tests and the continuum mechanics requirements in the limit of low shear rates and frequencies are confirmed. © 1990.
