Crystallographic damage evaluation and life prediction in the fatigue process using high energy white X-rays

研制了一种可附加在实验室X射线设备上的疲劳试验装置，并完成了一种配备有可测量局部区域的准直器的材料评定系统。为了评估单调加载和疲劳加载的损伤，使用高能白色X射线提取材料特性的变化。此外，还对模型进行了变形过程的数值模拟，并将实验获得的晶体结构反映在模型上。

Fatigue testing device which could be attached to the laboratory X-rays equipment was developed and the material assessment system equipped with the collimator which can measure a local area was completed. In order to evaluate the damage by monotonic loading and fatigue loading, change of material characteristics was extracted using the high energy white X-rays. Moreover, the numeric simulation of deformation process was made possible to the model on which the crystal structure acquired experimentally was reflected.
