摘要

For the adhesive contact of elastomers, we propose expressions to quantify the impact ofviscoelastic response on effective adhesion energy as a function of contact edge velocity. Theexpressions we propose are simple analytical functionals of the creep response and should besuitable for experimental data analysis in terms of measured rheologies. We also emphasizethe role of the coupling between local stress field at the contact edge and the macroscopicremote loading (far field). We show that the contrast between growing and receding contactsoriginates from the impact of viscoelastic response on coupling, while the separation processat the contact edge is similarly affected by viscoelasticity in both cases.
