Normal contact stiffness model considering 3D surface topography and actual contact status [PDF]
Mechanical Sciences, 2021 A normal contact stiffness model considering 3D topography and elastic–plastic contact of rough surfaces is presented in this paper. The asperities are generated from the measured surfaces using the watershed segmentation and a modified nine-point ...

Modeling the Contact Mechanics of Hydrogels [PDF]
Lubricants, 2019 A computationally lean model for the coarse-grained description of contact mechanics of hydrogels is proposed and characterized. It consists of a simple bead-spring model for the interaction within a chain, potentials describing the interaction between monomers and mold or confining walls, and a coarse-grained potential reflecting the solvent-mediated ...

Finite element based surface roughness study for ohmic contact of microswitches [PDF]
, 2012 Finite element method (FEM) is used to model ohmic contact in microswitches. A determinist approach is adopted, including atomic force microscope (AFM) scanning real contact surfaces and generating rough surfaces with three-dimensional mesh.
