Study on Low-Velocity Impact Behavior of Twaron® Fabric Subjected to Double-Impactor Impact from a Numerical Analysis Perspective

Abstract In the present study, a finite element impact model was developed and analyzed using commercial FEM code ANSYS® then validated via drop-weight experiment. Moreover, double-impactor models were designed with different distribution locations of two impactors to compare properties. A total 18 scenarios comprised asymmetric symmetric types performed. The effect location on resistance force duration time investigated: closer point is fabric center, longer time. addition, impactor failure deflection also investigated it concluded that regardless or scenario, smaller average distance between from fixed boundary, overall occurs. relevance energy absorption capacity identified. Furthermore, stress transverse deformation variation velocity behaviors investigated. These findings will provide important guidance for engineering soft body armor composite materials.
