A simple model for viscoelastic crack propagation

Abstract When a crack propagates in viscoelastic solid, energy dissipation can occur very far from the tip where stress field may be different $$r^{-1/2}$$ r - 1 / 2 singular form expected close to tip. Most theories of propagation focus on near region. Remarkable, here I show that simple theory which does not account for nature region results semiquantitative agreement with based consider both opening and closing solids, some processes must process zone. The is illustrated by new experimental adhesive interaction between silica glass ball silicone rubber surface. Graphic abstract
