【摘要】 夹杂物附近循环塑性应变场的细观力学实验研究洪宝宁徐涛（东南大学数学力学系，南京２１００１８）大量实验结果显示［１，２］，夹杂物是疲劳裂纹主要的萌生源之一，它对材料的疲劳力学性能影响很大．自５０年代起，人们已开始研究这类问题［３］，然而，受实验技术和...更多还原

【Abstract】 Depended on the observation of fatigue crack initiation near by inclusion on microscope,a method to calculate plasticity strain,utilizing series of microscope image, is presented. The statistical law of cyclical plasticity strain and its change,in course of fatigue crack initiation,is studied and analyzed.更多还原
