Modeling and Analysis of Human Liver by Using Finite Element Analysis

This work is focused on the construction of BIO-CAD modeling and analysis of human liver to satisfy the mechanical and biological characteristics. Developing the CAD model by using the data extracted from the CT scans. The 3D model of the human liver will be taken out from the CT scan datas using modeling tool CATIA. The 3DR concept can be applied for construction of profiles of human liver. The objective of this study is to develop robust finite element models of the liver. The organs are modeled for the first time as hyper viscoelastic materials and with individual constituents of each (viz. the capsule and veins). . To validate these models in vitro dynamic tests on porcine kidneys were performed, whereas dynamic impact test data from the literature on human liver were used. The optimize model of the human liver may attained by the way of interfacing CAD modeling tools and visual basic software. The FEM analysis will be carried out and verify the biological and mechanical characteristics using ANSYS.
