Effect of build parameters on the compressive behavior of additive manufactured CoCrMo lattice parts based on experimental design
Gülcan, O.; Simsek, U.; Çokgünlü, Okan; Özdemir, Mirhan; Şendur, Polat; Yapıcı, Güney Güven (MDPI, 2022-07)Due to their high specific strength, toughness, and corrosion and wear resistance characteristics, CoCrMo alloys are widely used in different industries and applications: wind turbines and jet-engine components, orthopedic ... -
An efficient design methodology for graded surface-based lattice structures using free-size optimization and enhanced mapping method
Şimşek, Uğur; Özdemir, Mirhan; Şendur, Polat (Elsevier, 2021-11-15)In this paper, a novel Free-size Optimization based Graded Lattice Generation (FOGLG) method, that generates the functionally graded lattice (FGL) structures using free-size optimization, is proposed. In addition, the ... -
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, ... -
A new sensitivity-based mapping scheme for topology optimization of graded TPMS designs
Parlayan, O.; Özdemir, Mirhan; Gayir, C. E.; Şimşek, Uğur; Kiziltas, G. (Springer, 2023-12)Graded TPMS topologies display excellent mechanical and thermal properties. Design schemes targeting optimal performance exist, but final reconstructed designs still suffer from performance degradation. To overcome this ... -
A novel design framework for generating functionally graded multi-morphology lattices via hybrid optimization and blending methods
Özdemir, Mirhan; Simsek, U.; Kiziltas, G.; Gayir, C. E.; Celik, A.; Şendur, Polat (Elsevier, 2023-05-25)Owing to its excellent mechanical properties, triply periodic minimum surfaces (TPMS) lattice structures have recently gained more interest in engineering applications. The superior properties of these structures make it ... -
