Ballistic Penetration Analysis of Soft Laminated Composites Using Sublaminate Mesoscale Modeling

چکیده
Ballistic impact mitigation requires the development of protective armor applications from composite material systems with good energy absorption and penetration resistance against threats, e.g., metallic projectiles. In this aim, high-strength high-stiffness soft fibrous materials (such as ultra-high molecular weight polyethylene—UHMWPE) are often used. The high specific strength feature is one main reasons for using these in ballistic applications. present investigation, experimental computational finite element (FE) studies were carried out to investigate behaviors layered targets. To end, a new FE multi-scale analysis framework simulations offered. proposed presents meso-scale sublaminate model, which applied Dyneema® cross-ply laminate order predict its behavior under impact. model implemented within an explicit dynamic code simulate continuum response each element. assumes through-thickness periodic stacking repeated configuration. addition, cohesive layer introduced delamination effect leading subsequent degradation deletion elements. This approach eliminates widely used costly elements installed at pre-specified potential paths between layers. Furthermore, in-plane damage modes fiber tensile, out-of-plane shearing) also accounted by employing failure criteria strain-softening. obtained quantitative results show correlation when compared relatively wide range experiments. Moreover, include evidence capturing mechanisms high-velocity modeling can be useful design tool.
