摘要: This work presents a computational material model of flexible woven fabric for finite element impact analysis and simulation. The is implemented in the non-linear dynamic explicit code LSDYNA. derivation utilizes micro-mechanical approach homogenization technique usually used composite models. accounts reorientation yarns architecture. behaviour achieved by discounting shear moduli free state, which allows simulation trellis mechanism before packing yarns. into LSDYNA as user defined subroutine. developed its implementation validated using an experimental ballistic test on Kevlar fabric. presented validation shows good agreement between utilizing present experiment.
