| 摘 要： | 电场活化聚合物（DielectricElastomer）属于大变形超弹性材料，基于ANSYS的超弹性模型对试验数据进行了拟合处理，选取出适合描述电场活化聚合物的超弹性模型——5参数Mooney—Rivlin模型、9参数Mooney-Rivlin模型和3次Ogden模型．依据非线性力学理论推导出了电场活化聚合物的工程应力计算公式，并利用单轴拉伸试验数据验证了这些计算公式的正确性．

| Abstract: | Dielectric elastome belongs to hyperelastic material with large deformations,the data was fitted into superelasticity models based on ANSYS,and determined that,Mooney-Rivlin model with five or nine parameters and Ogden model with three orders are suited the mechanical property of dielectric elastomers.According to the non-linear mechanical theory,the formula used in calculation of engineering tensile force of dielectric elastomers was derived,and the validity of the formula was proved by the experimental data. |
