With an ever increasing use of finite element (FE) analysis to study biomechanics involved in biomedical applications, many constitutive models have been developed to simulate a variety of biomaterial behaviors. These models not only have nonlinear, hyperelastic properties, undergoing finite deformation, such as the Holzapfel–Gasser–Ogden (HGO) model [1], but can also incorporate microstructural [2], viscoelastic [3], growth and remodeling [4,5], active contraction [6], or fatigue damage characteristics [7]. Consequently, these models vary in functional forms and sometimes involve time series and complex integrations. The implementation of such experimentally derived, user-defined material models in commercial FE packages such as abaqus (Simulia, Providence, RI) can be challenging, which may pose a barrier for the widespread use of these material models.
