Experimental studies are conducted to investigate the dynamic shear properties of thick magnetorheological elastomers
(MREs) which are affected by increasing the thickness, as well as the percentage of iron particles contained in these
materials. MREs with thicknesses of 25.4mm, 19.05mm, 12.7mm, 6.25mm and 3.05mm and with various iron particle
percentages are studied. A dynamic double-lap shear test setup is designed and built to conduct the experimental study.
The results demonstrate that the thickness of MREs significantly affect the material properties in the "off" state, that is,
when no magnetic field is applied. However, in the "on" state, when the material is activated by a magnetic field, the
thickness of the sample does not show a significant effect on the change in storage modulus induced by a magnetic field.
This change remains constant for all samples with different thicknesses under the same magnetic field.
