|Issue Date:||1995||Citation:||Shim, V.P.W.,Tan, V.B.C.,Tay, T.E. (1995). Perforation of woven fabric by spherical projectiles.

ScholarBank@NUS Repository.||Abstract:||Rectangular specimens of Twaron fabric are subjected to impact perforation by 9.5 mm diameter spherical steel projectiles at speeds ranging from 140 m/s to 420 m/s. This plain woven fabric is commonly employed in flexible armor applications. Its perforation response is examined in terms of residual velocity, energy absorbed, and resulting deformation patterns. The existence of a critical or transition impact velocity is observed. Differences in creasing and deformation induced in specimens are also demarcated by this transition impact velocity. Effects of difference in boundary conditions on yarn breakage are also noted. Finally, a numerical model, based on an initially orthogonal network of pin-jointed bars interconnected at nodes, is formulated to simulate the fabric.||Source Title:||American Society of Mechanical Engineers, Applied Mechanics Division, AMD||URI:||http://scholarbank.nus.edu.sg/handle/10635/75062||ISSN:||01608835|
