The discrete element method (DEM) has shown its powerful potential in simulating the behavior of granular materials under loading. Available macroscopic DEM results are consistent with laboratory observations. However, plenty of numerical microscopic information are unverified because 3-D microscopic experimental results are rare. The Magnetic Resonance Imaging (MRI) is a non-invasive technique which has been used medically for several years. Engineering application of MRI is rapidly expanding. MRI will provide necessary information to verify the numerical results from DEM. To study simple shear tests with MRI, a nonmagnetic simple shear device was manufactured. This paper will present the nonmagnetic simple shear device and the experimental results of simple shear tets using MRI.
