    • Hierarchical NURBS and a higher-order phase-field approach to fracture for finite-deformation contact problems 

      Hesch, C.; Franke, M.; Dittmann, M.; Temizer,İ. (Elsevier B.V., 2016)
      In this paper we investigate variationally consistent Mortar contact algorithms applied to a phase-field approach to brittle fracture. Phase-field approaches allow for an efficient simulation of complex fracture problems, ...
    • Metamaterial-based wireless RF-MEMS strain sensors 

      Melik, R.; Unal, E.; Perkgoz, N.K.; Puttlitz, C.; Demir, H. V. (2010)
      Approximately 10% of the fractures do not heal properly because of the inability to monitor fracture healing. Standard radiography is not capable of discriminating whether bone healing is occurring normally or aberrantly. ...
    • Microstructural association between mechanical behavior with bending fracture surfaces in Astaloy CrA sintered parts alloyed by Cu and C 

      Khorsand H.; Ghaffari, M.; Ganjeh, E. (Elsevier Ltd, 2014)
      Application of powder metallurgy technique, a method presenting both economic and technical concepts for producing sintered parts, has been expanding in automobile and other engineering industries. Powder metallurgy parts ...
    • Nested metamaterials for wireless strain sensing 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Santoni, B.; Kamstock, D.; Puttlitz, C.; Demir, H. V. (IEEE, 2009-12-28)
      We designed, fabricated, and characterized metamaterial-based RF-microelectromechanical system (RF-MEMS) strain sensors that incorporate multiple split ring resonators (SRRs) in a compact nested architecture to measure ...
    • Peridynamics review 

      Javili, A.; Morasata, R.; Oterkus, E.; Oterkus, S. (SAGE, 2018)
      Peridynamics (PD) is a novel continuum mechanics theory established by Stewart Silling in 2000. The roots of PD can be traced back to the early works of Gabrio Piola according to dell’Isola et al. PD has been attractive ...
    • Theoretical limits of the multistacked 1-D and 2-D microstructured inorganic solar cells 

      Yengel, E.; Karaagac H.; Logeeswaran V.J.; Islam, M.S. (SPIE, 2015)
      Recent studies in monocrystalline semiconductor solar cells are focused on mechanically stacking multiple cells from different materials to increase the power conversion efficiency. Although, the results show promising ...
