Impact of a rigid sphere onto a high-strength plain-weave Kevlar KM2 ® fabric was modeled using LS–DYNA ® focusing on the influence of friction and material properties on ballistic performance. Quasi-static friction was experimentally determined and incorporated into the model. Two clamped edges and two free edges were used as boundary conditions to correlate the model to an experimental...
In order to examine the role of friction during ballistic impact of high-strength fabric structures, a commercially available finite element analysis code (LS-DYNA) was used to model the ballistic impact of a rigid sphere into a square patch of plain-weave fabric. Two types of boundary conditions were applied on the fabric: four edges clamped and two opposite edges clamped. Simple Coulomb friction...
