| Research Abstract |
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.
