An isotropic elastic modulus was calculated from the unloading curve with an assumed Poisson ratio of 0.3, while hardness was defined as the maximal force divided by the corresponding contact area. The greater the modulus, the stiffer the material, or the smaller the elastic strain that results from the application of a given stress. The tooth was restored with a cast Ni … Although the general proportionality constant between stress and strain in three dimensions is a 4th-order tensor called stiffness , systems that exhibit symmetry , such as a one-dimensional rod, can often be reduced to applications of Hooke's law.
