Description
Finite element analysis (FEA) can be a powerful tool for studying the biomechanical behavior of human tissues, offering insights into the performance of biological systems under various loading conditions. However, the finite element analysis has been applied sporadically to the elbow joint so far [1]. This presentation outlines the process of developing a finite element model of the human elbow joint system, emphasizing geometry creation and material property implementation.
The modeling workflow begins with the acquisition of bone geometry through computed tomography. These datasets are processed to segment and reconstruct three-dimensional anatomical structures, ensuring accuracy in capturing intricate geometrical details. Subsequently, the elbow ligaments are modeled manually based on anatomical literature sources. The 3D geometries are converted into finite element meshes, striking a balance between computational efficiency and model fidelity.
Material property definition is a crucial step in simulating realistic biomechanical behavior. Bones are assigned orthotropic properties to replicate their complex material behavior, while ligaments are modeled as hyperelastic materials to account for their nonlinear stress-strain response.
This presentation will provide a walkthrough of the geometric modeling and material property assignment. The challenges and solutions associated with finite element simulations of biological tissues will be introduced, fostering a deeper understanding of its applications in biomechanical research.
