A general 3D contact smoothing method based on radial point interpolation

作者：

Highlights：

• A general 3D contact smoothing method using radial point interpolation is proposed.

• The method constructs local contact surfaces with polynomial and radial bases.

• The constructed surface is smooth and passes exactly through the surface nodes.

• The method shows good approximation in both coordinates and normal vector.

• It can effectively reduce contact force oscillation and solve the chatter problem.
