摘要

摘要: 基于ABAQUS有限元软件结合VC++6.0程序设计，建立了含不同铺层角度、不同排列密度形状记忆合金（SMA）纤维的复合材料层合板有限元模型。将基于Brinson本构模型的SMA分段线性超弹性模型以及判断复合材料层内失效的三维HASHIN失效准则编译至ABAQUS/VUMAT子程序，使用界面单元模拟复合材料层间区域，建立了SMA复合材料层合板的低速冲击损伤及冲击后剩余强度数值模拟方法。对比了不含SMA纤维层合板、含SMA纤维层合板、含普通金属丝层合板在不同冲击能量下的损伤响应。进一步分析了SMA纤维体积分数和直径变化对冲击响应的影响。冲击后剩余压缩强度模拟结果表明：冲击能量为16 J时，含体积分数25%、直径0.5 mm的SMA纤维层合板的冲击后剩余压缩强度相比不含SMA纤维层合板提高5.78%、相比含普通金属丝层合板提高4.69%。随着SMA纤维体积分数提高，层合板的抗低速冲击能力增强，当体积分数一定时，较细的（0.3 mm）SMA纤维比粗的（0.6 mm）SMA纤维对层合板的抗低速冲击能力增强效果更好。

Abstract: This study established 3D finite element analysis models of composite laminates containing SMA wires of different angles and different distance intervals by combing ABAQUS software platform and VC++6.0 program designing.The SMA piecewise linear model derived from Brinson constitutive model to describe the SMA superelasticity and the 3D HASHIN failure criterion to predict intralaminar damage of composite laminates were compiled as ABAQUS/VUMAT subroutines.Interlaminar damage was modeled with cohesive element.Numerical simulation method of the low-velocity impact damage behaviour of composite laminates containing SMA wires and compression-after-impact was proposed.This study compared the damage behaviour of laminates with and without SMA wires,as well as ordinary metal wires at different impact energy.Compression-after-impact (CAI) simulation results indicate that the CAI strength of laminates containing SMA wires with volume friction of 25% and diameter of 0.5 mm,is increased by 5.78% compared with laminates not containing SMA wires,and by 4.69% compared with laminates containing ordinary metal wires at impact energy of 16 J.Furthermore,computation results of SMA wires volume friction and diameter value effecting on the impact behaviour show that laminates' anti-impact ability becomes stronger when volume friction increases.When volume friction keeps constant,the enhancing effect on the laminates' anti-impact ability with SMA wires of smaller diameter (0.3 mm) is better than that with larger diameter (0.6 mm).
