Nanoindentation was conducted on sand grains to measure the Young's modulus, hardness, and fracture toughness of individual sand grains. An inverse problem solving approach was used to determine the stress-strain relationship of sand by allowing finite element simulated load-displacement relationship to agree with measurement data. A cube-corner indenter tip was used to induce cracks emanating from the corners of the indenter tip to measure the fracture toughness. X-Ray Diffraction (XRD) technique was used to determine the crystal structure of sand grains. ©2010 Society for Experimental Mechanics Inc.
