Distortion-minimized de-homogenization for optimization of cell-size distribution in TPMS structures
A wavenumber-difference minimization de-homogenization method for TPMS cell-size optimization reduces strain-energy error from 63.6% to 0.8% versus the homogenized model and yields 50.1% stiffness gain over uniform structures in FE analysis.
