Abstract
Boundary condition is an important factor for the impact behavior of fabrics. In the present work, the effect of boundary condition on the impact behavior of fabrics was investigated modeling the impact conditions in a finite element software program. In the numerical simulations, fabric boundary condition and impact velocity were used as variable parameters and their effects were discussed in terms of fabric deformation and energy absorption capacity. Based on the study, the significance of boundary condition gradually diminishes as impact velocity increases. However, at low velocities, fabrics with free edges provide enhanced energy absorption performance in comparison to those with fixed edges. In addition, fabric deformation turns to local scale increasing impact velocity however, at low velocities, deformation is extended over a wider area on the fabrics.
