Data for: Experimental and finite element analyses of contact behaviors between non-transparent rough surfaces
The data shared here are mainly about the evolution of real contact area and surface separation. The contact behaviors of three contact pairs were observed by employing the X-ray computed tomography technology. The detailed data of he real contact area versus contact pressure curves are shared in the Supplementary Material. The surface separation of contact pair 1-3 under each contact pressure are also presented in the Supplementary Material. These surface separation data are 201 × 201 height matrixes, representing the 2 mm × 2 mm square regions extracted from the centers of each contact pairs.
