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

研制了可附加在实验室x射线设备上的疲劳试验装置，并完成了配备准直仪的可局部测量的材料评估系统。为了评估单调载荷和疲劳载荷对材料的损伤，利用高能白x射线提取了材料特性的变化。同时，对实验得到的晶体结构模型进行了变形过程的数值模拟。

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.
