Objective: To calculate changes of rat tibial density induced by mechanical load with the finite element method.
Method: A three-dimensional computer model was formed by processing the industrial CT image of rat tibia; bone remodeling results were predicted by using the internal bone remodeling theory presented by Beaupre in conjunction with the finite element method.
Result: The increments of the elements density and its distribution plot were obtained.
Conclusion: The simulation results agree well with the results of the biological experiment, so the simulation results were proved to be accurate.
