Abstract: To study the strain distribution of the micro-defect cartilage under rolling load and to verify the accuracy of the numerical simulation. The strain around the defect were compared and analyzed with the methods of experiment and finite element simulation. Compared to other location, it was observed that the strain around the defect was larger, but the strain away from the defect was evenly distributed. Comparing the strain curve of experiment and simulation, it could be found the results were basically consistent regardless of in surface or bottom of the defect. The defect had distinct effects on mechanical properties of the cartilage under rolling load, and simulation results were approximately consistent with the experiment, meanwhile, it also made the reliability of simulation data demonstrated.

Key words: cartilage defects, rolling load, finite element analysis, cartilage experiment
