中文摘要：

针对目前金属磁记忆检测技术只能定性地确定应力集中区的位置，无法对应力集中区进行定量评估的问题，在研究外界载荷与构件表面应力分布关系的基础上，给出了构件处于弹性阶段时应力与磁导率之间的数值关系，并构建了金属磁记忆的检测系统，试验研究了外加载荷、提离及扫描路径对构件表面空间金属磁记忆信号的影响，研究结果为推进金属磁记忆的定量化研究奠定了基础。

英文摘要：

The metal magnetic memory（MMM） testing technology can only be qualitatively determine the location of the stress concentration zone, but can not quantitatively evaluate the stress concentration. On the basis of studying of the relationship between the external load and surface stress distribution, this paper derived the numerical relationship between stress and magnetic permeability of the elastic stage of the component, constructed the metal magnetic memory testing system, and studied the influence of the load, lift off and the scan path on the magnetic memory signals. The results laid the foundation for advancing the quantitative study of metal magnetic memory.
