  • 摘要:

    针对厚胶层复合材料黏接结构,采用有限元法对其中发生黏接界面弱化、胶层内聚弱化时的超声反射/透射系数进行了仿真计算。在仿真模型中,利用弹性薄层物理场边界模拟了常规理论推导中的弹簧模型边界条件,通过改变胶层材料的弹性常数实现了对胶层内聚状态变化的模拟。仿真计算结果表明:随着黏接界面弱化程度的加剧,超声反射/透射系数频谱曲线将向低频方向偏移,而超声反射/透射系数角谱曲线将向大角度方向偏移;随着黏接结构中胶层内聚弱化程度的加剧,对应超声反射/透射系数频谱、角谱曲线的偏移趋势与发生黏接界面弱化时的情况一致。研究成果解决了利用有限元法对厚胶层复合材料黏接结构中黏接界面、结构胶内聚层进行模拟处理的问题,且仿真结果和理论计算结果吻合良好。
