On analytical modelling to predict of the ballistic impact behaviour of textile multi-layer woven fabric

In this study, an analytical model is developed for an investigation of ballistic impact behaviour of 2D plain-weave fabrics. This model is based on both energy conservation and strain wave theory. Also, reflections of deformation waves are considered. The model can predict the evolution of parameters during an impact event continuously in terms of time and particularly, the limit speed of fabric perforation. Different phases during an impact event are analysed and discussed. The effects of the size of the fabric and the distance between layers are also studied. The results of this new model have been compared with experimental data. (C) 2012 Elsevier Ltd. All rights reserved.
