Investigating the normal and tangential peeling behaviour of gecko spatulae using a coupled adhesion-friction model
Saipraneeth Gouravaraju, Roger A. Sauer, Sachin Singh Gautam
The present work investigates the normal and tangential peeling behaviour of a gecko spatula using a coupled adhesion-friction model. The objective is to explain the strong attachm…
