In this paper we, using the viscoelastic, correspondence principle. consider the energy fracture criteria for a variety of linear viscoelastic solids. This principle arises because of the similarity which exists between the governing viscoelastic equations after Laplace transforms with respect to time and the corresponding untransformed elastic equations. We may therefore use this correspondence to write down immediately the Laplace transforms of the associated viscoelastic expressions. By inverting these transformed...

In this paper we, using the viscoelastic, correspondence principle. consider the energy fracture criteria for a variety of linear viscoelastic solids. This principle arises because of the similarity which exists between the governing viscoelastic equations after Laplace transforms with respect to time and the corresponding untransformed elastic equations. We may therefore use this correspondence to write down immediately the Laplace transforms of the associated viscoelastic expressions. By inverting these transformed equations, we may thus finally obtain formulae describing the energy fracture criteria of Maxwell, standard linear and Burgers solids, respectively.The analysis of this paper investigates the application of the energy balance fracture criteria to linear viscoelastic bodies. It is shown that:(a) The energy release rates of viscoelastic cracked bodies may be divided into two parts. One describes the effect of retarded elasticity, another part describes the effect of viscous flow;(b) Burgers solids, as well as Maxwell solids, exists a critical state. Because of the viscous flow, this state will arrive sooner or late:(c) The crack wilt propagate with high speed as soon as critical state of cracked bodies arrives;(d) In contrast to Maxwell and Burgers bodies, for standard linear cracked bodies, there exist a value of the load below which the critical state will never occur, exceed which then they will attain to the critical state sooner on later.

在本文,我们应用粘弹对应性原理探讨了各种线粘性固体的能量断裂判据。这项原理由于在对时间的Laplace变换后的基本粘弹性方程与相应的未经变换的弹性方程间存在相似性而成立,所以我们可利用这一对应性直接写出相关的粘弹性表示式的Laplace变换。于是,反演这些变换了的方程,我们最终分别得到表述Maxwell固体、标准线性固体和Burgers固体的能量断裂判据公式。本文的分析探讨了能量平衡断裂判据对线粘弹体的应用。它表明: (α) 粘弹性裂纹的能量释放率可分成两部分,一部分反映了延迟弹性效应,另一部分反映了粘性流效应; (b) 和Maxwell固体一样,Burgers固体也存在临界状态。由于粘性流的缘故,这一临界状态迟早要到来; (c) 裂纹体一旦到达临界状态,裂纹就将以高速扩展; (d) 与Maxwell物体和Burgers物体相反,标准线性裂纹体存在这样的一个载荷值,低于它时,永不会产生临界状态;高于它时,迟早会陷于临界状态。

The creep of concrete considering the delayed effect of elasticity is a deve-lopment of the applied creep theory. The procedure of estimating the stress re-distribution due to creeping of concrete of a segmentally cast continuous stru-cture loaded at different age of concrete, can be simplified by use of the mo-dified modulus of elasticity E.=E/1+ρφ, but the determination of the coeffi-cient ρ in [2] involves a lot of diagrams based on different ages of loadingτ_?.,theoretical thickness of members h_(?), the final yielding flow φ_(fk) and de-layed effect of elasticity φ_d,that leads to a complicated computer work. Thecoefficient ρ proposed by the author here taking account of delayed effect ofelasticity gives a result well consistent with that calculated by the former co-efficient. Derivation of formulas for calculating stress redistribution by finite ele-ment method is given in this paper, and some examples by hand calculation arealso given as an illustration.

计入弹性延迟影响的混凝土徐变是徐变实用理论的发展。采用混凝土徐变换算弹性模量E_φ=E/(1+ρφ),计算由不同加载龄期构件组成的超静定结构徐变内力重分布,可使计算简化。文献[2]根据不同加载龄期τ_o、构件的理论厚度h_(th)、最终流变值中φ_(f,k)及延迟弹性影响φ_d作出了大量图表,实现电算有较多困难作者按老化理论的狄辛盖尔公式推导,得到换算弹性模量公式中的龄期系数ρ=1/(1-e~(-φ)-1/φ,以此得到的内力量分布结果与用精确龄期系数计算的结果甚为接近。文中还采用有限元法推导了超静定结构徐变内力重分市的计算,并手算了几种类型的例题。
