✦ Synopsis

This paper presents a hydro-mechanical model for hysteretic damping force prediction of an electrorheological (ER) damper which can be applicable to a small-sized passenger vehicle. A mathematical model which well describes physical flow motion of the hydraulic system is formulated. Then, a cylindrical type of ER damper is devised and its hysteretic behavior is empirically evaluated in the damping force versus piston velocity domain. The measured damping characteristics are compared with those predicted from the proposed hydro-mechanical model. In addition, the averaged error between the predicted and measured damping force is calculated in order to evaluate the model accuracy.

## Abstract A model for prediction the stress‐strain behavior of particulate composite over wide ranges of filler concentration and composite deformation has been developed through combination of Anderson's and Yilmizer's model. The constitutive equations are extracted from first law of thermodynam
