摘要
对高强度材料 40 2钢进行了低周疲劳性能实验 ,通过应变为 0 .2 5 %到 1 % ,1 0级别 40根有效试样恒应变控制实验 ,给出了 40 2钢的应变疲劳曲线图和应变疲劳特性参数 ,为对 40 2钢建造的船舶结构进行疲劳分析提供了可靠的实验数据 .
The fatigue behavior test of the high_strength steel 402 was introduced.In the experiment,the amplitude of strain varies from 0.25% to 1%,in ten steps,under steady strain control.Data of 40 effective samples were gained.The strain_cycle for curves and fatigue property parameters of 402 steel were presented.The experimental data for fatigue analysis of ship structures made of 402 steel were provided.
