粘弹性固体中张开裂纹的扩展

On opening crack propagation in viscoelastic solids

B. N. J. Persson

摘要:

我们表明,在粘弹性固体中的裂纹扩展的Erosson-Brener理论给出了一个粘弹性断裂能因子$G/G_0 = 1+f$,这是几乎相同的粘弹因子使用的粘性区模型。我们还讨论了有限尺寸效应和评论使用的裂纹扩展理论的“固体”的粘弹性模量,在零频率消失。

英文摘要:

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.
