摘要

摘要: 为分析超高分子量聚乙烯（ultra-high molecular weight polyethylene, UHMWPE）的应变率效应及其对超高速碰撞特性的影响规律，采用万能材料试验机和分离式霍普金森拉杆对UHMWPE纤维束进行静、动态拉伸实验，获得了不同应变率下材料的应力-应变关系，并进一步开展了UHMWPE纤维织物的超高速碰撞数值模拟。结果表明，UHMWPE的拉伸模量和强度均随应变率的升高而逐渐增大。随着材料应变率敏感系数的增大，防护结构对弹丸动能的吸收率呈现先减小后增大的趋势。

Abstract: To analyze the strain rate effect and its influence on the dynamic response of ultra-high molecular weight polyethylene (UHMWPE) subjected to hypervelocity impact, the stress-strain relation of UHMWPE at different strain rates loading were obtained through universal material testing machine and Hopkinson bar experimental system. Furthermore, strain rate effect on the hypervelocity impact response was analyzed by numerical simulation. The results show that the tensile modulus and strength increase with the rise of strain rate. With the increase of the strain rate sensitivity index, the energy absorption ratio of the protective structure against the projectile decreases at the beginning followed by an increasing trend.
