Abstract
In the present study, a contact problem between an indenter and a half-anisotropic elastic surface with the micropattern is analyzed under normal and tangential forces considering friction. Surface Green's function, the discrete convolution and the fast Fourier transform method are used to calculate displacements on a contact area, and the conjugate gradient method is employed for calculating a contact pressure, the contact area, shear tractions, and a stick-slip region, respectively. The influences of the indenter profile and material anisotropy of the surface with the micropattern on the friction property are investigated. Spherical and logarithmic profile- indenters are used in the analysis. As the result, it was found that the ratio of stick region and the coefficient of friction of the logarithmic profile indenter were larger than that of the spherical indenter.
