Abstract
This paper aims to evaluate a device whose purpose is to obtain superficial parameters of bodies in contact. A numerical study with the Finite Element Method is used to evaluate the contact between the two bodies that make up the cited device. Two different cases are analyzed, first an evaluation within the elastic domain of the material, where the obtained results can be confronted with the analytical solution proposed by Hertz. Subsequently a more complex case is conducted, where the strain-strain correlation is non-linear, a configuration that does not have an established analytical solution.
