Tensile and Compressive Behaviors of Smart Electrorheological Materials

초록

This paper presents experimental results of tensile and compressive behaviors of smart electrorheological(ER) materials. Two different ER materials ; chemically treated starch particles and polymethylaniline particles are synthesized followed by devising a sqreeze mode type apparatus associated with motion controller and data acquisition system. The field intensity, electrode velocity and initial gap are chosen as important test parameters that influence on the tensile and compressive characteristics. The maximum tensile stresses are evaluated at each condition and compared between two ER materials.
