Experimental studies and effective finite element modelling of foot deformation in standing

In this work, a full scale subject specific FE foot model is developed to simulate the deformation of human foot under a standing position similar to a navicular drop test. The model used a full bone structure and effective embedded structure method to increase the modelling efficiency. Navicular drop tests have been performed and the displacement of the navicular bone is measured using 3D image analysing system. The experimental results show a good agreement with the numerical models and published data. The model is verified by comparing the numerical data for simple standing against subject specific navicular drop test. The detailed deformation of the navicular bone and factors affecting the navicular bone displacement and measurement are discussed.
