Dynamic characterization and optimization of additively manufactured TPMS lattice structures
Şimşek, Uğur (2021-08-19)Additive manufacturing (AM) has opened new avenues for the manufacturing of structures to achieve challenging engineering tasks. Triply periodic minimal surface (TPMS) lattices, a unique example of such structures, exhibits ... -
The effect of curvic coupling joints on the roto rdynamic characteristics of gas turbines with tie-shaft
Şimşek, Uğur; Şendur, Polat; Yaşar, A. (Canadian Acoustical Association, 2019)The importance and use of curvic coupling joints are garnering interest in many aero-engine rotordynamics applications thanks to their benefits such as lower stress, higher service life, reliable positioning, precise ... -
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 ... -
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. Functionally graded lattice (FGL) structures, a major class of such structures, developed using topology ... -
Modal characterization of additively manufactured TPMS structures: comparison between different modeling methods
Şimşek, Uğur; Akbulut, Aykan; Gayir, C. E.; Başaran, Cansu; Şendur, Polat (Springer Nature, 2020-10-14)The use of lattice structures has received increasing interest in various engineering applications owing to their high strength to weight ratio. Advances in additive manufacturing technologies enabled the manufacturing of ... -
Parametric studies on vibration characteristics of triply periodic minimum surface sandwich lattice structures
Şimşek, Uğur; Arslan, T.; Kavas, B.; Gayir, C. E.; Şendur, Polat (Springer Nature, 2020-10-07)Additive manufacturing has opened new avenues for the manufacturing of structures to achieve challenging engineering tasks. Gyroid, a unique example of such structures, exhibits many attractive properties, such as high ...
