Abstract
The present experiments consider the shock loading of porous samples under statically evacuated, atmospheric, and pressurized interparticle air conditions. An additively manufactured foam with interconnected pores, made from a titanium alloy, is used as the sample material. Loading by a moderate amplitude shock wave has shown that the effect of the internal air on the mechanical response is noticeable for the sample under pressurized conditions, differing from the responses at atmospheric and evacuated conditions. These observations agree with considerations of the air effect within a two-phase constitutive modeling approach.
