Witryna2 sty 2024 · According to this model, the low velocity impact is defined as the impact event whose impact velocity is not more than 10 m/s [ 10 ]. In contrast to the two other impacts, the low velocity impact allows the target enough time to respond and no stress wave propagation effect needs to consider. WitrynaExperimental studies on the high-velocity impact on GLARE composites are often performed using a high-speed gas gun. GLARE 5 specimens, with various thicknesses and lay-up configurations (2/1, 4/3 and 6/5), clamped at the edges were tested under several high-velocity impact loadings, ranging from 130 to 347 m/s [77].
