Concrete structures can suffer damage from the shock waves caused by explosions. However. the damage can be mitigated in practice by increasing the size of the energy-absorbing interlayers to improve the antiknock performance of the concrete. The aim of this paper is to investigate the energy-absorbing capability of a composite structure of polyurethane-foamed aluminum and concrete. https://cosmeticssquadets.shop/product-category/puzzles/
