A STUDY ON THE EFFECT OF TORSIONS ON THE STRENGTH OF ADHESIVE CONTACT
Geckos and many insects can not only adhere robustly to rough surfaces hutalso detach easily upon movement.Study the special ability has attracted a lot ofresearch attention recently.It will inspire us to develop wall-climbing robots,adhesive materials and bandages with superior properties and so on.For thebiomimetic applications the reversible adhesion mechanism is an important topic.In the present study,a JKR-model under combined tensile/torsion loading is usedto mimic the detachment process.Our analysis indicates that torque has asignificant effect on the strength of adhesion (e.g.pull-off force,critical contactradius and detachment work).The results obtained shed some new light on thereversible adhesion mechanism in biological systems and may be helpful for thedesigning of biomimetic adhesive materials in microelectronics and roboticsapplications.
