Abstract

ABSTRACT In the present study, two types of MRE with different concentrations, and circular and rectangular shapes having thicknesses from 6.35mm to a maximum of 25.4mm are prepared. These samples are tested under quasi-static compression and quasi-static double lap shear. It is observed that the measured off-state shear modulus has large variations with increase in the thickness of the sample. The measured shear modulus from the double lap shear test results, as well as the Young's modulus from the compression tests at zero-field, follows a logarithmic trend. With the increase in applied magnetic field, it is observed that the change in modulus shifted from a linear at lower field to a non-linear trend at higher fields. In addition it is observed that the controllability of MRE is more in the compression mode than in the shear mode . Keywords : Thick magnetorheological elastomers, shear , compression, damping, stiffness 1. INTRODUCTION Magnetorheological elastomers (MREs) are made by mixing micro-meter sized magnetizable particles with a non-magnetic elastomeric matrix. MREs are often referr ed to as the solid-state analogues of MR fluids
