Elastomer Testing: The Risk of Using Uniaxial Data Only for Fitting Mooney-Rivlin Hyperelestic Material Model
Original language description
Monney-Rivlin constitutive model is often used for characterization of hyper elastic rubber-like materials. To obtain material constants for the model, only a uni-axial tension data set is frequently used. Though it is regularly used for its easiness of getting data though simple practical, the method considered less accurate. To analyze the discrepancy in the method, a detailed examination was done with Monney-Rivlin two parameter model. This paper discusses the variation related to three basic load curves, i.e. uni-axial, equi-biaxial and pure shear. For visual observation of fitted data dispersion, two data fitting cases were considered. First one was with data fitting through only uniaxial data while combination of both uni-axial and pure shear experimental data curve fitting was used in the second case. Detailed one to one comparison of curves was done for accurate estimation of variation. In the later stage of the paper, preliminary investigation was done as to find out a possibility of forecasting equi-biaxial load curve for the available data.
