Research in Biomechanics (2001-2007)

1. Study of the knee ligaments at high flexion angles

The objective of this study was to develop and validate a rigid-body spring model of the knee to predict the forces in the major ligaments at high flexion angles.

A whole knee finite element model was built. It was published in Medical & Biological Engineering & Computing (2010).

2. Assessment of four talar component designs

The goal of this work was to develop finite element model for contact between the talar component and the bone. Thus, assess four designs of the talar component under different loading conditions.

A finite element contact model between the bone and the talar component was built.

3. A new approach for traction force microscopy

The goal of this project was to identify each pair of beads by a pattern recognition algorithm, and apply the finite element method to compute the cell traction forces.

Traction forces of cell were computed inversely from the displacement field by the finite element method. It was published in Journal of Theoetical Biology (2006) and Computer Methods in Biomechanics and Biomedical Engineering (2008 and 2010)

4. Simulation of the spine tissues with fiber reinforcement

The goal of this project was to simulate the 15 layers of fibers in annulus. The fiber orientation and Young's modulus vary in each layer.

5. Finite element simulation of soft tissues in the dynamic process

The project was aimed to develop finite element program to simulate soft tissues, which includes coupling of solid, fluid and ion phases, and involves large deformation and viscoelastic properties.

It was published in Computer Methods in Biomechanics and Biomedical Engineering (2006) and Journal of Mechanics in Medicine and Biology(2010).

6. Simulation of the human abdominal aortic aneurysm

The goal of this project was to study the mechanical behavior of abdominal aortic aneurysm under internal pressure with hyperelastic material model.

7. Axisymmetrical finite element models of a mouse knee

The goal of this project was to study the mechanical behavior of a mouse knee after depletion of cartilages.
