Experimental research on aluminum foam dynamics performance

This paper chooses the remit foam aluminum by Shanghai co., LTD provides high pressure filtration method is used to make the opening of aluminum foam material. System research of relative density and strain rate changes on the relative density is high (> = 0.255) of aluminum foam materials shock stress - strain behavior, deformation failure mechanism and the influence law of energy absorption characteristics. These studies can not only expand the awareness of foam metal mechanical behavior, but also on the domestic industrial production of the performance of the foam aluminum material design, optimization and production preparation plays a guiding role.
