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