A damaged elasto-brittle material constitutive relation in incremental form which consideres anisotropy of both material and damage is presented in this paper.The formula calculating the tensors (including the damage modulus,the effective elastic modulus and the kinetic elastic modulus as we-ll) are also derived. And based on this elastc-brittle damage theory and me-thod,the structural finite element procedure- taking local damage into account and its application to simulate damage-failure process of composite plate has been given. Finally the calculating results of the damage process of a glass-fiber woven/epoxy composite plate with a central holl under tensile lo-ading have been shown in the form of equi-damage lines and their change.

本文提出了一种增量形式的受损弹脆性材料的本构关系,此关系考虑了材料与损伤两者的各向异性。而且,导出了损伤模量、有效弹性模量以及动态弹性模量等张量表达式。根据本文提出的理论和方法,给出了考虑局部损伤的结构有限元方法,并应用于模拟复合材料板的损伤一破坏过程。最后,受拉伸的带中心圆孔的玻璃纤维布/环氧树脂复合材料板损伤过程的计算结果用等损伤线图形显示出来。

This paper proposes the kneepoint coordinate formula of damage broken lines and two stage fatigue damage cumulative rule by means of the analysis of lots of fatigue damage test data and theory research. The damage broken line in the paper is closer to experimental data than Miner damage line and the estimation method of fatigue life can be used for various of multilevel loading. Experimental verification has shown that the error that the new method estimates fatigue life is more noticeably decreased than that of Miner's rule.

通过对大量疲劳损伤试验数据分析和理论研究,提出了不同加载顺序下的损伤折线拐点坐标公式及二段式疲劳损伤累积规律。本文提出的损伤折线比Miner损伤线更接近试验数据,疲劳寿命估算方法能用于各种加载情况。试验验证表明,本文方法估算寿命误差比Miner法显著降低。

There are several opinions about the fatigue equivalent damage lines studied broadly at present. On the basis of fatigue test under high-low two stresses loading, the paper testifies that the equivalent damage lines do not parallel each other and tend to converge slightly over the fatigue limit. The problems of quantitative expression of equivalent damage lines, the slope change of the lines and life prediction are also discussed.

关于疲劳等损伤线的研究目前存在几种观点。本文根据高低二级应力作用下的疲劳寿命试验,验证了等损伤线互不平行且向下汇聚。还讨论了等损伤线的表达式,斜率变化和二级载荷下的疲劳寿命估算等问题。
