Mechanical Behavior of Chain-Link Wire Nets under Pressure from a Warhead: Quasistatic Experiments and Simulations

Wire nets woven from high-strength steel wires have been used as applique armor against attack by short-range weapons. In this study, the mechanical behavior of chain-link wire under pressure a warhead was investigated quasistatic experiments and simulations. First, new rig, device, were designed; tests conducted; deformation, fracture nets, force vs. displacement curves obtained analyzed. Then, numerical approach Finite element (FE) model developed, considering contacts between in inner connections, mesh material. By comparison with experimental data, FE are shown to be reliable predicting warhead. Finally, parameters net size angles further using validated model, suggestions for initial design discussed.
