Abstract: Greenwood and Tripp (GT model) have proposed that the contact analysis of two rough surfaces (two-rough-surface contact model) could be considered as an equivalent rough surface in contact with a rigid flat (single-rough-surface ...

Abstract: For real engineering surfaces contact, most asperities come into contact in a configuration of shouldertoshoulder instead of aligned headon. In this work, a threedimensional (3D) model of two identical elastic–plastic ...
