A Nonlinear Viscoelastic Model for Adipose Tissue Representing Tissue Response at a Wide Range of Strain Rates and High Strain Levels
Artikel i vetenskaplig tidskrift, 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.
