Abstract: Quasi-static
squeezing process of electrorheological(ER) fluid is studied. The mean
compressive stress of ER fluid during squeezing process is measured
under different electric fields. The Williams' s squeeze theory based on
the generalized bi-viscous model is applied to calculate the variation
of compressive stress with the amount of compression. It is found that
the experimental and theoretical curves agree with each other, implying
that the theoretical description of squeeze process of ER fluid is
fairly reasonable.
