Abstract

As is well known, the solution of analytical elastic contact problems [1, 2] is limited to a small number of specific contacts. For this reason, various numerical approaches were proposed to solve contact problems. The use of conventional numerical solving methods is however limited by the large volume of computation due to the use of fine meshing of the assumed area of contact with an important number of nodes. Various methods are proposed in literature to reduce the computing time and power needed to solve contact problems. In order to highlight the dependence between micro-contact parameters and the mechanical properties of the materials in contact, the present paper proposes the numerical modeling of micro-contacts using the Conjugate Gradient and Fast Fourier Transform technique (CG + FFT), [3, 4], and its adaptation to the micro-contact range. Model validation is performed by comparing the obtained results with the classical Hertz model, for various contact body shapes. The obtained results show very good agreement between the numerical and analytical results, thus validating the proposed numerical model.
