Based on the Penn's experimental data, a consistently compressible Mooney-Rivlin model is developed for the vulcanized rubber. First, the Penn's experimental data are re-analyzed, which show the near incompressibility. Next, the incompressible Mooney-Rivlin model and three conventional types of compressible model are studied for the vulcanized rubber, which exhibit an apparent inconsistence with the incompressible model due to the dissimilar initial shear modulus. Finally, a consistently compressible model with extra constants is proposed, which obeys the normalization conditions and the consistent conditions, and a procedure to identify model constants is suggested, and then applied to the Penn's experimental data. The consistently compressible Mooney model is eventually established for the vulcanized rubber, and then compared with other four hyper-elastic models.

基于 Penn 实验数据的硫化橡胶始终可压缩的 Mooney-Rivlin 模型

根据 Penn 的实验数据,为硫化橡胶开发了一个始终可压缩的 Mooney-Rivlin 模型。首先,重新分析了宾大的实验数据,显示出接近不可压缩性。接下来,针对硫化橡胶研究了不可压缩的 Mooney-Rivlin 模型和三种常规类型的可压缩模型,由于初始剪切模量不同,它们与不可压缩模型存在明显的不一致。最后,提出了具有额外常数的一致可压缩模型,该模型遵守归一化条件和一致条件,并提出了识别模型常数的程序,然后将其应用于宾夕法尼亚大学的实验数据。最终为硫化橡胶建立了一致可压缩的门尼模型,
