“…Although there are many similarities between the fabric model developed here and the particleelement models described in References [21,22], there are also significant differences. The present work combines a density interpolation of the type used in [21] with a thermodynamic model of the type used in [22].…”

SUMMARYHigh-strength fabrics are employed in a wide range of ballistic protection and blast mitigation applications. They are normally used in a multilayer configuration. General numerical models of impact, perforation, and fragmentation processes in multilayer fabrics must account for complex contact-impact dynamics and include general thermomechanical coupling. A hybrid particle-element formulation has been developed to simulate impact and perforation in plain weave fabrics. Simulation results show good agreement with experiment, for fragment simulating projectile impacts on both aramid and ultra high molecular weight polyethelene soft armor materials.

“…Shivarama and Fahrenthold (2004) suggest a hybrid particle-finite-element method, which avoids tensile stability and numerical fracture problems and eliminates the requirement for special treatment of particle-to-element contact-impact. A modified version of this hybrid particle-finite-element formulation is proposed in Park and Fahrenthold (2005).…”

“…In recent years a number of coupled particle-element and hybrid particle-element methods have been introduced, in an attempt to combine the best features of finite element methods and particle methods, in a unified numerical formulation. One such approach is the hybrid particle-element formulation developed by the first author and coworkers [1,2]. This formulation employs particles and elements in tandem.…”
