Adherence of a hyperelastic shell on a rigid planar substrate

A hyperelastic shell with spherical cap geometry is compressed to a rigid planar substrate. Using Maugis’ graphical method and a numerical approach, the quasi-static adhesion-detachment trajectory, the interrelation between applied load, approach distance and contact radius, and the critical pull-of...

Zusammenfassung:A hyperelastic shell with spherical cap geometry is compressed to a rigid planar substrate. Using Maugis’ graphical method and a numerical approach, the quasi-static adhesion-detachment trajectory, the interrelation between applied load, approach distance and contact radius, and the critical pull-off parameters are determined for ranges of materials stiffness, shell thickness, shell depth and interfacial adhesion energy.
