Abstract

ADIPOSE TISSUE is a loose connective tissue distributed in two main anatomic depots including subcutaneous and visceral. Since in many pathological conditions and diseases associated with ADIPOSE TISSUE alteration, the micro-components of ADIPOSE TISSUE undergoes considerable changes from a mechanical characteristics point of view, it is quite vital to present an accurate structural technique for modelling tissue microstructure. Accordingly, this paper presents a structural model based on the main components of ADIPOSE TISSUE and the interaction between them. Adipocytes were considered as fluidic spheres and extracellular matrix was modeled as solid media. The interaction between these two different phases was simulated by solving well-known fluid-structure interaction (FSI) problem. In order to obtain the constitutive parameters for ECM, finite element simulation results were fitted to experimental uniaxial compression test data. To make a comparison between the performances of different constitutive models, three conventional hyperelastic models were used for describing the mechanical behavior of ECM. The agreement between experimental data and simulation results confirms that the presented technique has a high potential for modeling ADIPOSE TISSUE microstructure, in both normal and pathological condition. Considering the accuracy and mathematical complexity, results show that Yeoh hyperelastic model has a better performance than the two others. In all three models, results reveal that the stiffness of ADIPOSE TISSUE ECM is ~ (2-3) times higher than that of the ADIPOSE TISSUE.
