“…In other words, the sizes of samples in previous simulation work are smaller than those in actual ballistic impact experiment [4][5][6][7][8][9][10][11][14][15][16] . Cunniff [18] applied a sample holder with three sizes of apertures to clamp a single-layer fabric.…”

“…Given the complexity of hierarchical structure of ballistic fabrics, the influence factors from the structure are considerable [1] , for instance, the strength, the pattern, the warp and weft yarn density and so on. Among those numerous influence factors, the inter-yarn friction is outstanding and vital and its effects on the ballistic performance have been investigated by some researchers, such as Hearle et al [2] , Briscoe and Motamedi [3] , Duan et al [4,5] , Zeng et al [6] , Rao et al [7] , and Sun et al [8] , Minh et al [9] , Gogineni et al [10] , Nilakantan et al [11] .,Sun et al [12,13] , Zhou et al [14] ，Wang et al [15] and Daset al [16] .…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights  Higher inter-yarn friction will make the energy absorption rate increase monotonously.  Higher inter-yarn friction will make the response mode of fabric more globalized.  Near zero friction, strain energy(SE) is the dominant mechanism of a fabric while at higher  inter-yarn friction, kinetic energy(KE) becomes the dominant one  An maximum inter-yarn friction exists for frictional dissipation energy(FDE) absorption

“…This approach leads to a significantly reduced computational expense compared to a full 3D yarn length scale model. Similar yarn length scale and multi-scale modeling approaches include the works by Gogineni et al 165 , Gu 166 , Sun et al 167 , Grujicic et al 142 , Jia et al 168 , Yen et al 169 and Jiang et al 170 . There is limited yarn level multi-scale modeling that takes into account the fiber-fiber interactions and fiber properties other than axial tension.…”

Ballistic impact onto flexible woven textile fabrics is a complicated multi-scale problem given the structural hierarchy of the materials, anisotropic material behavior, projectile geometry-fabric interactions, impact velocity and boundary conditions. Although this subject has been an active area of research for decades, the fundamental mechanisms such as material failure, dynamic response, multi-axial loading occurring at the lower length scales during impact are not well understood. This paper reviews the recent advances in modeling and experiments of Kevlar ballistic fibrils, fibers, yarns and flexible woven textile fabrics pertinent to the deformation modes occurring during impact and serves to identify topics worthy of further investigation that will advance the basic understanding of the phenomena governing transverse impact. This review also explores on aspects such as homogeneous versus heterogeneous behavior of yarns consisting of individual fibers and the inelastic transverse behavior of the fiber which is not considered in the previous review papers on this topic.

“…However, the volumetric deformation or inter-yarn friction cannot be precisely reproduced due to oversimplification of the contact geometry, even though they are important parameters (Sockalingam et al, 2014). To address these issues, Shockey et al (1999) was the first to propose a 3D yarn level model, followed by more recent studies (Nilakantan and Nutt, 2014;Grujicic et al, 2008;Gogineni et al, 2012); details regarding yarn transverse deformation or contact interaction within the fabric can be modeled. Zhu et al (2011) and Dong and Sun (2009) were the firstand only authors so far -to the authors knowledge, to simulate yarn pull-out.…”

a b s t r a c tWith the increasing usage of woven fabrics in various applications, an understanding of inter-yarn friction characteristics is useful for effective employment of such fabrics. Although the yarn pull-out test is a recognized method to ascertain yarn mobility within a weave, the physics governing yarn pull-out has not yet been fully examined, and previous finite element models were unable to reproduce the results of yarn pull-out tests. Consequently, fabric response involving yarn pull-out has not yet been well-understood in terms of the influence of inter-yarn friction and yarn crimp. The work undertaken provides insights into this by proposing a new yarn pull-out test procedure, which involves in-plane and out-of-plane pull-out; the latter is relevant to projectile penetration of fabric, during which yarns are often pulled out of the fabric plane. Pre-tension is also applied to fabric specimens, and its influence on the response is analyzed. The energy absorbed during out-of-plane pull-out is quantified, and yields insights into fabric performance. A finite element model is then developed to simulate yarn pull-out tests. To characterize inter-yarn friction, a Coulombic description that considers both static and kinetic friction, is implemented. The numerical model is able to describe both in-plane and out-of-plane yarn pull-out. The model is validated and used to identify mechanisms that restrain yarn mobility during yarn pull-out and how pre-tension affects this mobility. The local fluctuations in the experimental force-displacement curves are captured by the simulation, and are found to be caused by periodic alteration of the original crimped yarn profile during pull-out. Simulation results also show that most of the energy is dissipated by friction during yarn pull-out, and that the fabric stores strain energy. Pre-tension has a significant influence on both frictional energy dissipation, and strain energy in the fabric. Strain energy is found to be more sensitive to pre-tension than frictional dissipation, indicating that excessive restraint of yarn mobility may result in premature yarn failure.
