Prospect of producing metallic composites with controlled macrostructure via deformation processing is examined. The study combines numerical analysis(FEM) with experimental observations both made under plane strain and aims to determine conditions that would lead to macrostructure in which the reinforcements are refined with large aspect ratio and homogeneously distributed throughout the structure. The role of the inherent properties of the constituent phases and that of the geometric parameters, i.e., relative size and spacing of reinforcing layers of the initial composite production are considered. The study shows that incorporation of continuous reinforcements in the initial composite is advantageous in that it always ensures a uniform of distribution of reinforcements, even in cases where they rupture into fragments. Problems associated with conditions that lead to desirable macrostructure on the one hand and the ease of fabrication on the other are discussed.


Mechanical behaviour of Al2O3-ZrO2 minicomposite reinforced glass matrix optomechanical composite
Dericioğlu, Arcan Fehmi (Informa UK Limited, 2003-08-01)
To understand the effect of a 'mesh-structured reinforcement' on the optical and mechanical properties of optomechanical composites, a unidirectional Al2O3 fibre-ZrO2 matrix minicomposite reinforced glass matrix optomechanical composite has been fabricated. By regular alignment of the minicomposites in the glass matrix as part of the 'mesh structure' a high degree of optical transparency is obtained in the composite; this transparency is proportional to its 'optical window' regions. The mesh structured rein...
Stress analysis of symmetric aluminum composite-laminated beams under a bending moment: Materially nonlinear only
Sayman, O; Belevi, M; Altinhan, M (SAGE Publications, 2005-01-01)
In this study, an elastic-plastic stress analysis is carried out on symmetric laminated composite beams subjected to a bending moment. The composite beam is to be strain hardening. The Bernoulli and Euler hypotheses are assumed to be valid. The Tsai-Hill theory is used as a yield criterion in the solution. The solution is carried out for (90 degrees/0 degrees)(2), (30 degrees/-30 degrees)(2), (45 degrees/-45 degrees)(2), and (60 degrees/-60 degrees)(2) orientations. The bending moment is to be found the hig...
Metal mesh filters based on Ti, ITO and Cu thin films for terahertz waves
Demirhan, Y.; Alaboz, H.; ÖZYÜZER, LÜTFİ; Nebioglu, M. A.; Takan, T.; Altan, Hakan; Sabah, C. (Springer Science and Business Media LLC, 2016-02-01)
In this study, we have investigated the spectral performance of resonant terahertz (THz) bandpass filters which were produced from thin films with a metal-mesh shape. The aforementioned filters were fabricated from titanium, copper and indium tin oxide thin films on fused silica substrates by UV lithography with an array of cross-shaped apertures. Since the mesh period, cross-arm length and its width specify the spectral characteristics of the filters, we were able to reveal the performance of these filters...
Grain-Scale Investigations of Deformation Heterogeneities in Aluminum Alloys
GÜLER, BARAN; Simsek, Ulke; Yalçınkaya, Tuncay; EFE, MERT (2018-04-25)
The an isotropic deformation of Aluminum alloys at micron scale exhibits localized deformation, which has negative implications on the macroscale mechanical and forming behavior. The scope of this work is twofold. Firstly, micro-scale deformation heterogeneities affecting forming behavior of aluminum alloys is investigated through experimental microstructure analysis at large strains and various strain paths. The effects of initial texture, local grain misorientation, and strain paths on the strain localiza...
Vibration damping behavior of epoxy matrix composites reinforced with carbon fibers and carbon nanotubes
Avil, Esma; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2019)
The main objective of this study was to investigate contribution of the nonfunctionalized multi-walled carbon nanotubes (CNT) on the vibration damping behavior of first neat epoxy resin and then unidirectional and bidirectional continuous carbon fiber (CF) reinforced epoxy matrix composites. Epoxy/CNT nano-composites were produced by ultrasonic solution mixing method, while the continuous CF reinforced composite laminates were obtained via resin-infusion technique. Vibration analysis data of the specimens w...
