The method exploits the original idea of accounting for the shape of roughness as a correction to the normal gap function, rather than explicitly discretizing roughness with higher-order numerical interpolation schemes. The resulting interface finite element with eMbedded Profile for Joint Roughness (MPJR interface finite element) is derived and its implementation as a user-defined element is comprehensively described.
