In the present paper, a plane stress elastic-plastic fracture model-the strip necking zone model is proposed on the basis of the experimental results given by Schaeffer, Liu and Ke. It may be regarded as an extension of Dugdale Model. With this model, the calculations by finite element method incorporating plastic deformation theory or plastic incremental theory are both carried out to determine the crack opening displacement. The calculated results are compared with the Burdekin's design curve and some published experimental results. The analysis indicates that the nominal strains vary with different gauge lengths. Therefore Burdekin design curve is on the safe side when the nominal strains are taken at some definite gauge lengths. The calculated values of the crack opening displacements in this paper are in good agreement with the published experimental results.

本文根据文献对薄钢板试样的实验分析,提出一个平面应力的弹塑性断裂模型——带状颈缩区模型.将Dugdale模型推广到弹塑性变形场情形.用弹塑性全量理论和增量理论的有限元法,分别计算了具有中心裂纹的薄宽板受均匀拉仲情形的裂纹张开位移、应力应变场.结果表明Burdekin设计曲线在一定条件下才是安全的,本文计算的裂纹张开位移与一些实验测量结果符合良好.

Tn this paper, based on the plane stress strip necking zone fracture model, the stable craek growth processes of center cracked aluminum alloy panels, subjected uniform tensile load, are calculated based on large plastic deformation equation by finite element method. The failure criterion used is that the tensile strain at the crack tip readies the elongation of the material at failure. The calculated results are in good agreement with experimental data.
