Dependence of Adhesive Friction on Surface Roughness and Elastic Modulus
Daniel Maksuta, Siddhesh Dalvi, Abhijeet Gujrati +3
When adhesive elastomeric materials slide over hard rough surfaces at low velocities, there are two primary dissipative mechanisms that control how friction changes with sliding ve…
Crack-front model for adhesion of soft elastic spheres with chemical heterogeneity
Antoine Sanner, Lars Pastewka
Adhesion hysteresis can be caused by elastic instabilities that are triggered by surface roughness or chemical heterogeneity. However, the role of these instabilities in adhesion h…
Height-averaged Navier-Stokes solver for hydrodynamic lubrication
Hannes Holey, Andrea Codrignani, Peter Gumbsch +1
Modelling hydrodynamic lubrication is crucial in the design of engineering components as well as for a fundamental understanding of friction mechanisms. The cornerstone of thin-fil…
Efficient topology optimization using compatibility projection in micromechanical homogenization
Indre Jödicke, Richard J. Leute, Till Junge +1
The adjoint method allows efficient calculation of the gradient with respect to the design variables of a topology optimization problem. This method is almost exclusively used in c…
Scale-dependent roughness parameters for topography analysis
Antoine Sanner, Wolfram G. Nöhring, Luke A. Thimons +2
The failure of roughness parameters to predict surface properties stems from their inherent scale-dependence; in other words, the measured value depends on the way it was measured.…
Elimination of ringing artifacts by finite-element projection in FFT-based homogenization
Richard J. Leute, Martin Ladecký, Ali Falsafi +5
Micromechanical homogenization is often carried out with Fourier-accelerated methods that are prone to ringing artifacts. We here generalize the compatibility projection introduced…
