Abstract

A JKR (Johnson-Kendall-Roberts) formalism is used to extract the Young modulus, the contact radius, and the energy release rate simply from the retraction curve of a borosilicate glass colloidal probe from a polydimethylsiloxane (PDMS) surface using an atomic force microscope. PDMS samples ranged from perfectly elastic to those with incipient viscoelasticity. The dependence of the release rate energy with the crack speed is verified using a fracture mechanics-based method.
