Temperature dependent adhesive interfacial mechanical properties of EPDM film

  • 摘要: 采用双悬臂夹层梁(DCSB)试件对三元乙丙橡胶(EPDM)薄膜黏接界面Ⅰ型断裂的温度相关性进行了研究;采用线弹性断裂力学(LEFM)方法获取了黏接界面断裂能,将其与单轴拉伸所得内聚强度作为双线性内聚力模型(CZM)参数,对不同温度条件下双悬臂夹层梁试件的Ⅰ型断裂行为进行了数值仿真.结果表明:仿真与实验曲线偏差较大,偏差出现的原因主要是未经修正的线弹性断裂力学方法所求断裂能存在较大的误差,需对其进行修正.调整模型参数使仿真曲线与实验曲线重合,获取了黏接界面的准确力学性能参数,采用此参数得到的仿真结果与实验结果具有较高的吻合度,证明了模型的可适用性.
