J024063 Prediction of optimal material distributions for soft tissue using FEA

Abstract

In this study, the indentation tests of soft materials were performed to predict the internal distributions of the materials which are assumed as the human soft tissues. These results of tactile tests were applied to the finite element analysis which is combined with the genetic algorithm search technique. In the results of these trials, the predicted distributions and the size of the foreign particles by the simulations have good agreements with the specimens in especially using the hyperelastic definitions.
