Surface separation and contact resistance considering sinusoidal elastic–plastic multi-scale rough surface contact
The current work considers the multi-scale nature of surface roughness in a new model that predicts the real area of contact and surface separation as functions of load. This work is based upon a previous rough surfacemulti-scale contactmodelwhichused stackedelastic–plastic spheres tomodel themultiple scales of roughness. Instead, this work uses stacked 3D sinusoids to represent the asperities ...
متن کاملRole of Surface Roughness in Hysteresis during Adhesive Elastic Contact.
In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelas...
متن کاملElastic-plastic Contact of a Rough Surface with Weierstrass Profile
In this appendix, we list the expressions that characterize the response of an elastic-perfectly plastic solid with sinusoidal roughness to indentation by a rigid flat punch. The substrate is an elastic-perfectly plastic solid with Young’s modulus E, Poisson’s ratio ν and yield stress Y σ . The surface roughness has wavelength n λ and amplitude n g . In terms of these parameters, we define a ma...
متن کاملEarthquake Analysis of 3-D Structures on Sliding Foundation Using Yield Equation of the Contact Surface
A solution technique for the dynamic analysis of asymmetric base-isolated buildings, subject to earthquake ground motion, is presented. To develop the formulation, a yield surface as a function of both shear force and torsion moment of the sliding surface with rigid perfectly plastic behavior is constituted. To achieve the objective, the yield stress is defined by the friction coefficient throu...
