Research on Adhesion Pull-Off Behavior of Rigid Flat Punch and Viscoelastic Substrate by Tao Zhang, Yunqi Zhang, Kai Jiang

“…The adhesion contact mechanism is still unclear as the time-dependent viscoelasticity of soft materials. To clarify the adhesion interaction, the pull-off detachment between the rigid flat punch and viscoelastic substrate is explored considering the viscoelasticity of soft materials and rate-dependent adhesion. …”
