Engineered Cementitious Composites (ECC) are relatively new types of fiber reinforced cementitious materials with enhanced mechanical properties such as tensile strain hardening accompanying high tensile strain capacity. This is mainly attributed to close and multiple cracks with widths remaining under 60 µm which contributes to durability of ECC material. These properties are only achievable as a result of a micro-mechanical design that requires special ingredients that make ECC costly to be used alone, however it is possible to use ECC together with other construction materials such as steel and concrete. On the other hand, as a result of abundant binders and low water to binder ratio, ECC shrink more compared to other construction materials. In this paper, shrinkage properties including restrained shrinkage of four different ECC mixtures are determined along with the tensile creep behavior. Furthermore a new setup with the method and procedure to determine the tensile creep is given in details.

Investigation of structural and electronic properties of ZnCdTe ternary alloy nanostructures Kurban, Mustafa; Erkoç, Şakir; Department of Physics (2016) Nanostructures, including II-VI compound semiconductors, have attracted enormous attention in a wide range of applications of nanotechnology due to the unusual mechanical, electrical and thermal properties under varying size, geometry, temperature and pressure when compared to corresponding bulk materials. However, these properties are not directly measurable by experiments because of the methods or the availability of the experimental tools, so theoretical models and computations play an important role in ...
Investigation of novel geometrical design concepts for damping treatments Çavuş, Bertuğhan; Özgen, Gökhan Osman; Department of Mechanical Engineering (2022-11) Surface damping treatment concepts are developed utilizing viscoelastic materials as a damping layer where it is applied to the main structure. The main aim for adding these materials is to increase cyclic deformation in the frequency region of interest, which increases dissipated energy from the main structure. Constrained layer damping treatment is the most common, where the viscoelastic layer is constrained by a stiff top layer. Recently, a spacer or standoff layer has been added between the base and con...
Determination of mechanical properties of hybrid fiber reinforced concrete Yurtseven, Alp Eren; Tokyay, Mustafa; Department of Civil Engineering (2004) Fiber reinforcement is commonly used to provide toughness and ductility to brittle cementitious matrices. Reinforcement of concrete with a single type of fiber may improve the desired properties to a limited level. A composite is termed as hybrid, if two or more types of fibers are rationally combined to produce a composite that derives benefits from each of the individual fibers and exhibits a synergetic response. This study aims to characterize and quantify the mechanical properties of hybrid fiber reinfo...
Synthesis and characterization of Ti-based bulk amorphous/naocrystalline alloys for engineering applications Abdelal, Ali; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2004) Amorphous and bulk amorphous metallic alloys are an intriguing class of structural materials and possess a range of interesting properties, including near theoretical strength, high hardness, extremely low damping characteristics, excellent wear properties, high corrosion resistance, low shrinkage during cooling and almost perfect as-cast surfaces with good potential for forming and shaping. In this study, new Ti-based bulk amorphous alloys are tried to be modeled and synthesized. For that purpose, electron...
Experimental investigation of CNT effect on curved beam strength and interlaminar fracture toughness of CFRP laminates Arca, M. A.; Çöker, Demirkan (2014-06-20) High mechanical properties and light weight structures of composite materials and advances in manufacturing processes have increased the use of composite materials in the aerospace and wind energy industries as a primary load carrying structures in complex shapes. However, use of composite materials in complex geometries such as L-shaped laminates creates weakness at the radius which causes delamination. Carbon nanotubes (CNTs) is preferred as a toughening materials in composite matrices due to their high m...
