And the strain measurements were conducted under bending loads applied to the Ti specimen. The effect of skin tissue...

... ), SRSM is more efficient. Even though that previous study only used 2 strain measurements for optimization, 5400 FE simulations and 150 “chromosomal generations” or iterations were required for convergence, and the total computation time took 25–40 days. Although this study optimized two fewer material...
