A Nonlinear Viscoelastic Model for Adipose Tissue Representing Tissue Response at a Wide Range of Strain Rates and High Strain Levels
Journal article, 2018

Finite element human body models are nowdays commonly used to simulate pre- and in- crash occupant response in order to develop advanced safety systems. In this study a biofidelic model for adipose tissue is developed for this application. It is a nonlinear viscoelastic model based on the Reese et al. formulation. The model is formulated in a large strain framework and applied for finite element simulation of two types of experiments: rheological experiments and ramped-displacement experiments. The adipose tissue behavior in both experiments are represented well by this model. It indicates the capability of the model to be used in large deformation and wide range of strain rates for application in human body models.
