Engineers developed a way to quickly test metamaterial architectures and their resilience to supersonic impacts. They plan to use it to identify new metamaterial designs that could form the basis for ...
This chapter discusses helmet ballistic testing methodologies. It describes helmet design and suspension systems as well as current and proposed clay head forms used in the ballistic testing of ...
In my January 2024 column, I reported on a new ASTM test method for use in assessing the damage tolerance of sandwich composites under compression loading: the sandwich compression-after-impact (CAI) ...
CAMBRIDGE, MA – An intricate, honeycomb-like structure of struts and beams could withstand a supersonic impact better than a solid slab of the same material. What’s more, the specific structure ...
