Zusammenfassung der Projektergebnisse

It can be stated that the claimed aim of the project to extend the formalism of the MDR for the multi-scale indentation problem including the effect of adhesion for both a system of general non-axisymmetric indenters and a general linear elastic foundation has been achieved. It is shown that asymptotic modelling can make a bridge between MDR and BEM in multi-scale contact problems. The obtained asymptotic solutions can be used for evaluation of the multi-scale indentation test for soft biological tissues with the adhesion effect.
