Finite element analysis of effect of inter-yarn friction on ballistic impact response of woven fabrics

摘要: Abstract Friction has shown to have a significant effect in determining the ballistic impact performance of woven fabrics. Many efforts were made investigate how inter-yarn friction affects response fabrics past decades. However, fundamental understanding mechanics mechanisms works fabric panels still needs be established and improved. It is vitally important understand for example distribution stress magnitude yarns. This necessary failure yarns energy absorption event. paper presents detailed analysis on behaviour using finite element method. been found that stresses yarn surface sensitive frictional coefficient between crossing fabric.
