UHMWPE层合板抗侵彻性能的一种等效数值分析方法
Equivalent Numerical Simulation Method for Penetration Resistance of UHMWPE Laminate
摘要
Abstract
To enhance the modeling and computational efficiency of numerical simulations for penetration resistance in ultra-high molecular weight polyethylene fiber(UHMWPE)laminates,an equivalent mechanical model of UHMWPE laminates was established based on the theory of three-dimensional equivalent elastic constants,and a three-dimensional equivalent rapid simulation method suitable for predicting the penetration resistance of fiber composite laminates was developed.As verified by the UHMWPE laminates'penetration test data,the equivalent method can accurately simulate and predict the staged penetration characteristics of laminates by taking into account the influence of the fiber lay-up on the mechanical properties of the laminates,and the average errors for the ballistic performance of 9.1-60.0 mm laminates are less than 10%.The method bypasses the need for detailed modeling of fiber bundles and matrices,as required in mesoscopic scale numerical simulations,and eliminates the necessity of specifying individual fiber/resin ply orientations and inserting numerous bonding elements,as in quasi-mesoscopic scale simulations.关键词
