Coated contacts: a strain approach

Tribology International, 2003
A strain approach for the design of coated contacts is described, allowing a simple evaluation of the risk of coating failure, once the elastic modulus of the coating and the substrate and the coating thickness are known. Examples are provided for hard and soft coatings.

Strain-Induced Reversal of Charge Transfer in Contact Electrification†

Angewandte Chemie - International Edition, 2012
We have contact! Material strain can have a dominating effect on contact electrification. When a deflated (relaxed) balloon is rubbed against teflon, the teflon surface charges positively, but when the same balloon is inflated (strained), the teflon surface charges negatively.

The Strain Magnitude and Contact Guidance Determine Orientation Response of Fibroblasts to Cyclic Substrate Strains

Connective Tissue Research, 2000
When grown in a substrate subjected to cyclic stretching, most types of cells change orientations. This cell orientation response (COR) has been shown to be driven by axial substrate strain (the strain beneath and along a cell's long axis). However, it remains unclear whether COR depends on the strain direction (tension vs compression). Furthermore, in

Strain gradient plasticity analysis of elasto-plastic contact between rough surfaces [PDF]

open access: yesJournal of the Mechanics and Physics of Solids, 2016
From a microscopic point of view, the real contact area between two rough surfaces is the sum of the areas of contact between facing asperities. Since the real contact area is a fraction of the nominal contact area, the real contact pressure is much ...

Strain limiting for soft finger contact simulation

2013 World Haptics Conference (WHC), 2013
The command of haptic devices for rendering direct interaction with the hand requires thorough knowledge of the forces and deformations caused by contact interactions on the fingers. In this paper, we propose an algorithm to simulate nonlinear elasticity under frictional contact, with the goal of establishing a model-based strategy to command haptic ...
