Conference Object Citation - WoS: 1Citation - Scopus: 1Numerical and Experimental Studies of High Strain Rate Mechanical Behavior of E-glass/Polyester Composite Laminates(The American Society of Mechanical Engineers(ASME), 2010) Tunusoğlu, Gözde; Taşdemirci, Alper; Güden, Mustafa; Hall, Ian W.; Taşdemirci, Alper; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyQuasi-static ∼10-3 s-1) and high strain rate (∼850 s-1) compression behavior of an E-glass/polyester composite was determined in the through-thickness and in-plane directions. In both directions, modulus and failure strength increased with increasing strain rate. Higher strain rate sensitivity for both elastic modulus and failure strength was observed in the in-plane direction. A numerical model was developed to investigate the compressive deformation and fracture of an E-glass/polyester composite. Excellent agreement was demonstrated for the case of high strain rate loading. Also, the fracture geometries were successfully predicted with the numerical model.Conference Object Kompozit Alüminyum Köpüklerin Hazırlanması ve Mekanik Özelliklerinin Belirlenmesi(2015) Güden, Mustafa; Elbir, Semih; Yılmaz, Selahattin; Güden, Mustafa; 03.02. Department of Chemical Engineering; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyPreslenmiş tabletlerin ısıtılması yöntemi ile hazırlanan kapalı hücreli SiC-parçacık takviyeli alüminyum kompozit köpüğün köpükleşme ve basma mekanik testi özellikleri belirlenmeye çalışılmıştır. Bu özellikler aynı yöntemle hazırlanan saf alüminyum köpüğün özellikleri ile karşılaştırılmıştır. Sonuçlar, SiC-parçacık takviyeli köpüklerde köpükleşmenin ve plato gerilmesinin daha yüksek olduğunu göstermiştir.
