Abstract

An elastic modulus of single voxel was measured and analyzed to measure physical properties of materials. A tipless cantilever was used to measure the elastic modulus of the single voxel with the ellipsoid shape. Then allowing for the effect of deformation of the rest part on the result analysis

the contact model of elastic sphere on a flat surface was developed. In the base of calibrating the elastic constant of cantilever and analysis adhesion force

the force information from force curve was obtained and the elastic modulus of single voxel was calculated. At last

It is concladed that the elastic modulus of volex is generally lower than that of SCR500.
