Hierarchical Engineered Materials and Structures
Abstract
This project is concerned with a new class of light-weight, hierarchical engineered material systems designed to mitigate effects due to high intensity short duration loads, such as blast. A fundamental research program that combines elements of experiments, analysis and the conception of novel numerical tools to tackle several challenging issues are described. The proposed work will be focused on engineered materials and structures that are exposed to loads of high intensity and short duration. As a result, the design of the material will occur simultaneously with the design of the structure. The overarching issues this research addresses are the lack of fundamental understanding of the response of a structure made of a combination of materials and structural concepts (multi-material structures) at high strain rates. Towards achieving this goal, the static and dynamic response of honeycombs and filled honeycombs ave been studied. The filler material chosen is a elastomer. Several new results have been obtained as shown in the contents of this final report and these results shed new light on the utility of filled honeycombs as efficient energy absorbers under dynamic crush conditions.
