Abstract: The statistical microcontact models of Greenwood–Williamson (GW), Kogut–Etsion (KE), and Jackson–Green (JG) are employed along with the elastic bulk deformation of the contacting solids to predict the characteristics ...

Abstract: This work presents experimental contact stiffness measurements for various thin films as well as homogenous materials through pressing a flat punch onto a nominally flat rough surface. These materials are typically used ...

Abstract: Finite element (FE) simulations were performed to study yielding in single and bilayer (BL) film systems using a “yield zone mapâ€‌ approach. Onset of yielding was observed at the interface, substrate, surface, and film ...
