The additive manufacturing technology, among its many advantages, allows us to manufacture solids with controlled enclosed porosity. To the best of my knowledge, this was not doable with conventional machining technologies, but now this is done. In the attached document, the interested reader will find experimental results (both static and dynamic) describing the influence of the porosity on the specimen's performance. We show that while the volume fraction is indeed an important parameter, aas expected, the spatial arrangement of the voids is also of prime importance. We believe that similar future researches should yield a wealth of information which will ultimately yield to new or improved exisiting models. The paper has been accepted in the JAM, and I attach here the un-edited accepted version. Comemnts are of course welcome.
