Abstract
This paper investigates dynamic, frictional contact of a moving punch over the surface of anisotropic materials. An eigenvalue analysis of the governing equations is performed. The application of the complex function theory produces a singular integral equation exhibiting a non-square-root or unconventional singularity. Numerical tests demonstrate that both the friction coefficient and the moving velocity contribute to the contact behaviors under a moving punch with a flat or cylindrical profile. Furthermore, the present results illustrate that the surface in-plane stress possesses singularity and discontinuation at both edges of the flat punch and has a tensile spike at one edge of the cylindrical punch, which may account for the fatigue and fracture under the contact loading.
