ABSTRACT
In this paper, the performance of different hyperelastic constitutive models namely Money-Rivlin, Gent, Ogden and Arruda-Boyce to predict the dynamic characteristic of elastomeric components is investigated. An elastomeric engine mount is chosen as case study. Material Parameters of the different models are extracted by curve fitting on uni-axial stress-strain test data. Both static and dynamic response of the finite element model considering the hyperelastic constitutive models are compared with their measured counterparts and each other. To obtain frequency response function of the component for each model, at first considering proportional damping for elastomeric media, the transient analysis due to impulse excitation is performed on the component and then using FFT transformation, the frequency response function is achieved. The results show that hyperelastic constitutive models can be implemented in predicting both static and dynamic behavior of elastomeric components.
