Adhesive Contact

Un article de Surface du verre et interfaces.

Adhesive contacts play a central role in many technological areas. Efficient manufacturing processes require a tight control over the contamination of surfaces by particles. Energy efficient mechanical devices and reliable micromechanical systems demand better control over friction and lubrication. Key phenomena such as particle immobilization or release in filtration, controlled positioning in reproduction devices, settling of bio-organisms on surfaces in health or bio-technologies must be better understood for further progress. Understanding the adhesive contact is a key issue for surface functionalisation.

For linear elastic systems and their immediate extensions (linear viscoelastic), we investigate how the macroscopic response is impacted by the interplay between the physical mechanism of adhesion and the mechanical response of the materials.
