title = "An improved method to identify the evolution of rough surface contact by the elliptical asperity",
abstract = "The accurate estimation of real contact area is important to evaluate the contact resistance for engineering rough surfaces. In this work, an improved contact analysis method for calculating the real contact area of rough surface is proposed. Firstly, an elliptical asperity is introduced to represent the asperity peak with a large aspect ratio feature, which is different from the traditional spherical asperity. Subsequently, the real contact area and contact load under progressive indentation depth are identified by combining the Hertz theory for the fractal rough surface. Furthermore, a 3D finite-element model of rough surface is built and the mechanical simulation results are compared with the analytical methods. And the proposed method based on elliptical asperity compared with spherical asperity is more effective and shows a good agreement with the numerical simulation.",
