摘　　要：针对022Cr17Ni12Mo2不锈钢半圆形缺口件以及U形缺口件进行了一系列室温下的应力控制低周疲劳试验.应用Abaqus软件进行有限元模拟,采用非线性随动硬化、各向同性属性混合模型和单轴循环应力应变曲线描述材料的弹塑性特性.模拟结果与试验结果吻合.A series of the stress control low cycle fatigue tests were conducted at room temperature for 022Cr17Ni12Mo2 stainless steel semicircle-notched specimens and U-shaped specimens. Abaqus was applied for finite simulation. The mixture model of the nonlinearincidentalhardening and isotropic properties and uniaxial cyclic stress strain curve were adopted to describe the elastoplastic properties of materials. The simulation results accorded with experimental results.
