Abstract: | The use of phase shift-digital speckle pattern interferometry (DSPI) together with an optimization method for displacement prediction of a bone sample was evaluated. The proposed method is based on Particle-swarm Optimization (PSO) algorithm which used analytical data to obtain the bone Young’s modulus for Finite Element Analysis (FEA) simulations in order to compare with experimental displacements results from DSPI. A bone sample was used in the experiments for generating the displacements by using DSPI, PSO algorithm identified the optimized Young’s modulus and FEA was used to simulate displacements from the bone geometry model. Results presented good agreement between FEA and DSPI data showing error around 3%. This can be considered a potentiality of DSPI supported by optimization method and FEA for displacement prediction in bone samples. |
