Finite element analysis of impactor shapes effects on puncture damage of plain woven fabric

The article presented finite element analysis work on modelling impactor shape effects on plain woven fabric puncture damage. Woven fabric models were developed with ABAQUS finite element analysis software package. Large scale woven fabric models consisting of 112 yarns in both warp and weft direction were developed with ABAQUS preprocessor module prior to simulation analysis. Woven fabric model development procedure for finite element analysis was based on the validated uniaxial tensile model reported in the earlier publication. Four impactor shapes for the simulation were flat, hemispherical, conical and ogival. The simulation results were analyzed in terms of stress-strains, post-impact kinetic energy and damage evolution. The research proposed that crimp interchange and yarn extension are two important mechanisms in woven fabric puncture.
