Experimental and numerical modal characterization for additively manufactured triply periodic minimal surface lattice structures: Comparison between free-size and homogenization-based optimization methods
Özdemir, Mirhan; Simsek, U.; Kuşer, Engin; Gayir, C. E.; Celik, A.; Şendur, Polat (Wiley, 2023-06)Homogenization-based topology optimization (HMTO) is one of the most extensively used grading methods to generate functionally graded lattice structures (FGLs). However, it requires a precharacterization of the lattices, ... -
An integrated homogenization–based topology optimization via RBF mapping strategies for additively manufactured FGLS and its application to bandgap structures
Şimşek, Uğur; Gayir, C. E.; Kiziltas, G.; Şendur, Polat (Springer Nature, 2020)The manufacturing of lattice structures has been greatly facilitated thanks to the advances in additive manufacturing.
