Abstract

Prediction of adhesion is of great significance in the development of micro-electromechanical systems and medical devices to achieve reliable and cost-effective design. For this purpose, knowledge of material and surface properties and their role on adhesion is crucial. This paper employs a multi-asperity adhesion model providing a greater understanding factors influencing on phenomena of adhesion and this novel method can be used as a tool for effective design of materials and their contact in various devices. A dimensionless analysis, employing the π theorem, is presented based on the multi-asperity JKR adhesion model. The role of surface topography, material properties and the effect of asperity height distribution and its asymmetry on force of adhesion has been shown using dimensionless parameters. The application of the developed methodology is demonstrated through a case study on catheter design.
