A binary model of textile composites—II. The elastic regime

摘要: In a previous paper, new model called the Binary Model was formulated to describe behavior of textile composites with three-dimensional (3D) reinforcement. Here, detailed prescriptions are given for constitutive laws computational elements in terms properties constituent materials and geometry fiber The application studied is woven 3D interlock Predicted macroscopic elastic constants agree experimental values without use adjustable parameters. also shows how waviness nominally straight tows weaves affects statistics local stresses. Through-thickness reinforcement disorders stresses, but its effect found generally be much less than that tow current composites. For predicting onset failure, it inferred treating stochastic effects irregularity more important modeling influence configurations great detail.
