Abstract
A purpose of this laboratory is to investigate influence to give the better processing method in the model bending test of aluminum honeycomb materials for a processing result by sounding out lapis lazuli, the change of the dynamic moment. I performed bending to aluminum honeycomb materials while changing a dynamic processing condition and groped for a method to machine in an objective shape. The result of this study is connected directly with possibility of the expansion of the use of lightweight high-stiffness honeycomb materials. I investigated a method to predict the observation of the spring back phenomenon and spring back quantity when I made bending on an aluminum alloy honeycomb structure body this year.
