Overview The study of ballistic impact on Kevlar-reinforced gelatin is crucial for understanding body armor performance, behind-armor blunt trauma (BABT), and wound ballistics. Gelatin is widely used as a soft tissue simulant due to its mechanical similarity to human muscle tissue, while Kevlar (a para-aramid fiber) is a common ballistic-resistant material used in protective gear ...

The increasing threat of blast loads on critical underground infrastructure has necessitated advanced protective measures for tunnels. Ultra-High Performance Concrete (UHPC) has emerged as an excellent material for blast-resistant structures due to its superior strength and energy absorption capacity. When combined with Glass Fiber-Reinforced Polymer (GFRP) protection, UHPC tunnels can ...
