We show that the Persson-Brener theory of crack propagation in viscoelastic solids gives a viscoelastic fracture energy factor \(G/G_0 = 1+f\) which is nearly the same as the viscoelastic factor obtained using the cohesive-zone model. We also discuss finite size effects and comment on the use of crack propagation theories for “solids” with a viscoelastic modulus that vanishes at zero frequency.

粘弹性固体中开裂扩展的研究
我们表明，粘弹性固体中裂纹扩展的 Persson-Brener 理论给出了一个粘弹性断裂能量因子\(G/G_0 = 1+f\)，它与使用内聚区模型获得的粘弹性因子几乎相同。我们还讨论了有限尺寸效应并评论了裂纹扩展理论对粘弹性模量在零频率下消失的“固体”的使用。
