Theoretical Analyses of Interaction Forces Acting between Solid Surfaces Considering One-Dimensional Periodic Material Distribution: Radial Effects of Spherical Surface

The surface interaction stress distributions (pressure and shear stress) forces (normal force) between a sphere half-space with one-dimensional periodic material distribution are calculated numerically. is based on the Lennard-Jones (LJ) potential expressed as Fourier series. With minimum distance of 0.2 nm, size effects spherical radius stresses quantitively discussed. show strong correlations half-space. were by integrating acting surface. They at every position in distribution. We reveal dependence forces. Under conditions this study, normal force increases linearly, whereas exhibits local radius.
