Through the general analysis of energy, this paper, based on researches by H. Liebowitz and others, suggests that a non-linear energy rate can be taken as a fracture criterion. This criterion can be used not only to treat simple tensile mode non-linear fracture problems, but the mixed mode non-linear fracture problems as well.

As energy release, rates are not the direct solutions of the boundary-value problems of the cracked bodies, in principle, the expressions of energy release rakes for viscoelastic cracked bodies can not be obtained by direct use of the viscoelastic correspondence principle. Although in some special cases (constant load and constant displacement) this difficulty has been overcome by artifice, it is still necessary for us to discuss the G_i—K_i relationships for viscoelastic cracked bodies generally.As we have shown in our previous work, the energy release rates for viscoelastic bodies are egual to the rates of crack-closure energy. By using the solution of the crack-border stress and displacement fields for linear viscoelastic solids, the time-dependent G_i—K_i relation-ships for viscoelastic cracked bodies are derived from the computation of the rates of crack-closure energy. The main conclusion is that:1) The G_i—K_i relationships for viscoelastic cracked bodies are time-dependent. The energy release rate for viscoelastic cracked body can be obtained by multiplying the energy release rate of the corresponding elastic cracked body by a certain time-factor: f_(?) (t).2) The time-factors of the energy release rates are the products of the time-factors of stresses(or stress intensity factors) and the time-factors of displacements, f_(?)(t)=f_(?)(t)f_(?)(t).3) Time-factors of the energy release rates are different from each other among cracked bodies of different rheologieal models, different stress states(plane stress, plane strain or anti-plane-strain)and different conditions (assigning load or assigning displacement). The time-factors for all these cases are given in this paper.4) Using the results obtained here, we can generalize conveniently and immediately some results of the linear elastic mechanics of fracture to the cases of viscoelastic cracked bodies.

由于能量释放率不是裂纹体边值问题的直接解答,粘弹裂纹体的能量释放率原则上不能直接应用粘弹对应原理求得。在某些特殊情况(常载荷或常位移)下,这一困难虽然已被巧妙地克服,但仍有必要一般地讨论粘弹裂纹体的G_i—K_i关系。如我们在前文中指出那样,粘弹体的能量释放率等于裂纹闭合能量率。利用线粘弹体裂纹前缘的应力位移埸,通过计算这一裂纹闭合能量率,推导出了粘弹裂纹体的时间相依G_i—K_i关系。主要结论如下: 1) 粘弹裂纹体的G_i—K_i关系是时间相依的。粘弹裂纹体的能量释放率可从对应的弹性裂纹体的能量释放率乘以某时间因子f_(ig)(f)而得到。2) 能量释放率的时间因子等于应力(或应力强度因子)和位移的时间因子的乘积f_(ig)(t)=f_(iσ)(t)f_(iα)(t)。3) 不同流变模型、不同应力状态(平面应力、平面应变、反平面应变)及不同情况(给定载荷、给定位移)的裂纹体的能量释放率是不相同的。4) 采用这里得到的结果,可以很方便地立刻将线弹性断裂力学的某些结果推广到粘弹裂纹体的情形。

Due analysis has been made and it is found that the nonlinear energy release rate of orthotropic plate with a, crack is dependent on the biaxial load factor,
