The Mechanical Analysis Of Scaffold For Tendon Tissue Engineering Using Finite Elements Method

Objective Make mechanical analysis on the tissue engineering scaffold. Method In this paper, a 3D model simulating a kind of scaffold for tissue engineered tendon is established using finite element method. We delivered sufficient computation and analysis to the model under all kinds of forces possible. Results To that kind of model with long and narrow slots parallel to each other on its surface, the maximal stress occurred in the top corners of the bicephalous planes. When a force up to 0.01 Newton was added, we observed obvious transfiguration, and the model witnessed a collapse under the force up to 0.05 Newton. Conclusion It's reasonable and feasible to use FEM analysis in order to give some supports in theory in the aspect of how cells distribute on the scaffold.
