    Toughening Mechanism of Silicon Whiskers and Alumina Fibres (γ-Al2o3) Reinforced Ni-Al Matrix Composites Through “sintering + Forging”
    (Springer, 2023) Miskioglu,I.; Zambelis,G.; Gatamorta,F.; Aslan,O.; Bayraktar,E.
    In this study, the microstructural formation and static/dynamic compression behaviour of recycled Ni-Al-Cu matrix hybrid composites reinforced with silicon whiskers and alumina (Al2O3) fibres will be studied. It is intended to be an alternative to traditional alloys/composites used in the aeronautical industry. These composites generally are produced using by combined “sintering + forging” processes. The static and dynamic properties will be evaluated in detail, considering the relevant scanning electron microscopy (SEM) microstructures (including the distribution of reinforcement elements). © 2023, The Society for Experimental Mechanics, Inc.

    Numerical Modeling of Recycled Rubber Based Composites Reinforced With Glass Fibers at High Strain Rates
    (Springer, 2022) K-Cakir,G.; Aslan,O.; Bayraktar,E.
    Due to its high impact energy absorption properties, devulcanized recycled rubber based composites can be considered as a low cost candidate material for military applications which require lightweight protection against shock waves. This work aims at modeling of low cost devulcanized recycled rubber based composite behavior at high strain rates. In that framework, we established a continuum-based material model in order to capture the macroscopic behavior of the recycled rubber based composite material and numerically reproduce the results from the basic characterization tests. The model is implemented for Finite Element Analysis Software ABAQUS/Standard as a user subroutine UMAT for implicit nonlinear finite element calculations in order to simulate the behavior of several RVEs representing the microstructure of the composite and it is behavior at high strain rates. © 2022, The Society for Experimental Mechanics.

    Design of Recycled Aluminium (aa 7075+aa1050 Fine Chips)-Based Composites Reinforced With Nano-Sic Whiskers, Fine Carbon Fiber for Aeronautical Applications
    (CRC Press, 2023) Aslan,O.; Klinkova,O.; Katundi,D.; Miskioglu,I.; Bayraktar,E.
    In the frame of the research project that is going on, the mechanical properties of recycled gas atomized scrap aluminium (AA7075) based hybrid composites reinforced with nano SiC filler (whisker)+ Graphene Nano plateless (GNP) and fine carbon Fibers elements have been evaluated. Firstly, the mixture was homogenized by means of ball milling process during 4 hours. After hot compaction at 200°C compaction of the compositions the final specimens have been produced with the novel combined method called “SINTER+FORGING” at 650°C followed by relaxation treatment at 200°C during the 2 hours. This type of hybrid composite is used for aeronautical applications. Static and dynamic-Time dependent compression tests have been conducted. Interface and microstructure of these composites have also been evaluated by Scanning Electron Microscope (SEM). © 2024 selection and editorial matter, N. M. Nurazzi, E. Bayraktar, M. N. F.

    Design of Recycled Aluminium (AA7075)-Based Composites Reinforced with Nano Filler NiAl Intermetallic and Nano Niobium Powder Produced with Vacuum Arc Melting for Aeronautical Applications
    (CRC Press, 2023) Kasar,C.; Aslan,O.; Gatamorta,F.; Miskioglu,I.; Bayraktar,E.
    In the frame of the common research project, the mechanical properties of recycled gas atomized scrap aluminium (AA 7075)-based composites reinforced with nano filler NiAl intermetallic and niobium (Nb) elements have been evaluated. Firstly, the mixture was homogenized by means of a ball milling process for 4 hours. After cold compaction of the compositions, the final specimens have been produced with “vacuum arc melting” for aeronautical applications. Static and dynamic compression tests have been conducted. Additional tensile tests have also been carried out. Experimental results were compared with a finite element method. The interface and microstructure of these composites have also been evaluated by a scanning electron microscopy. © 2024 selection and editorial matter, N. M. Nurazzi, E. Bayraktar, M. N. F.

    A Numerical Approach To Simulating Oxidation in Thermal Barrier Coatings
    (Elsevier, 2020) Saeidi,F.; Gurses,E.; Aslan,O.
    Computational analysis and simulation of multi-physics phenomena taking place in coating systems is still a challenging task. Specifically, for ceramic coatings used as a system of protection for base materials against elevated temperatures, known as thermal barrier coating (TBC) systems, construction of continuum level models which can express coupled nonlinear phenomena has attracted great attention. Thermal stresses, oxidation, creep and numerous other mechanisms and phenomena makes it even harder to model and simulate the behavior of TBCs. In this article, a new numerical model which allows simulation of oxidation and thermally grown oxide (TGO) of bond-coat is presented. Phase field theory is used with finite strain formulation and implemented using user element subroutine (UEL) in ABAQUS software for finite element method. Results are compared with experimental data available for TGO in the literature. © 2020 Elsevier Inc. All rights reserved
