Structural blast design
Blast design is a necessary part of design for more buildings in the United States. Blast design is no longer limited to underground shelters and sensitive military sites, buildings used by the general public daily must also have satisfactory blast protection. Integrating blast design into existing …

Finite element modeling of energy-absorbing materials in blast-loaded structures
… such as foam or honeycomb are of interest in blast protection because of their ability to absorb energy through plastic deformation. They absorb a considerable amount of energy relative to their low density, and are investigated to determine if their energy absorbing abilities can be used to …

Fabrication and Compressive Behavior of Corrugated Aramid-Epoxy Cellular Solids
… A number of cellular solids can provide blast protection and absorb impact energy, but few perform well resisting blunt object (ballistic) penetration. In this thesis, a method is proposed for fabricating cellular solids from aramid-epoxy composites that can absorb impact energy and …

Counterterrorism civil engineering design
… choice of construction materials will mitigate blast effects; windows, doors, HVAC and firefighting systems should be designed to save lives and to not cause more injuries! Finally, the major driver for a successful blast protection is designing redundancies to carry the additional loads imposed …

Behavior of reinforced concrete column-beam joint subjected to close in blast loads with polyurea and FRP sheets
… concrete (RC) column-beam joint under close-in blast loads using finite element modeling in LS-DYNA with an Arbitrary Lagrangian-Eulerian (ALE) formulation. Failure is captured through element erosion based on maximum principal strain. The study employs concrete with a compressive strength of …

Machine learning methods for architected materials
… applications such as lightweight structures for blast protection, efficient heat exchangers, or battery electrodes with large specific surface area. They have an intricate microstructure which is a feature that makes them both attractive to use but also difficult to design with. In the pursuit of …
