Abstract: Fabrics are an extremely important element of body armors and other armors. Understanding fabrics requires understanding how yarns deform. Classical theory has shown very good agreement with the ...

Abstract: Ballistic tests were performed on single-yarn, single-layer and ten-layer targets of Kevlar® KM2 (600 and 850 denier), Dyneema® SK-65 and PBO® (500 denier). The objective was to ...

Abstract: Glass impact experiments were designed at three different scales—0.22-cal, 0.375-cal, and 0.50-cal—named after the diameter of the bullets. Four experimental series were conducted at the three ...

Abstract: Numerical and analytical simulations of projectiles penetrating brittle materials such as ceramics and glasses are a very challenging problem. The difficulty comes from the fact that the yield ...
