Effect of thickness and pre-crack length on delamination of unidirectional l-shaped laminated composites Gozluklu, Burak; Yavas, Denizhan; Çöker, Demirkan (null; 2012-12-01) It is widely assumed that delamination initiates at the curved region of the Lshaped laminate leading to loss of loading carrying capacity. However, as shown in this paper, under certain conditions a second failure mode in thick L-shaped laminates is observed in which a secondary crack initiates at the arm region. Delamination in L-shaped laminates is modeled using dynamic (explicit) finite element analysis in conjunction with cohesive zone methods. The 2-D model consists of 24 plies of unidirectional CFRP ...

Effect of coarse aggregate size and matrix quality on ITZ and failure behavior of concrete under uniaxial compression Akcaoglu, T; Tokyay, Mustafa; Celik, T (2004-08-01) Effects of coarse aggregate size and water/cement (w/c) ratio of the matrix on the formation of interfacial transition zone (ITZ) and subsequently on the failure process of concrete under uniaxial compression were studied. For this purpose, a series of experiments were designed and carried out on mortars with two different w/c ratios containing single spherical steel aggregates of different sizes. The ITZ properties and the failure process of concrete were investigated through tensile strength tests both be...
Effect of particle size and slag content on the early hydration of interground blended cements Cetin, Can; Erdoğan, Sinan Turhan; Tokyay, Mustafa (2016-03-01) Three blended cements prepared by intergrinding 6-35% slag with clinker and gypsum, and a control portland cement, were sieved to yield 0-10 mu m, 10-30 mu m, 30-50 mu m, and >50 mu m subgroups. Clinker/slag/gypsum contents, and oxide compositions of the subgroups differed significantly from the unsieved cements. Fine subgroups always contained more gypsum and had lower slag-to-clinker ratios than coarse subgroups. Heat evolution was investigated up to 48 h using isothermal calorimetry. Contribution of slag...
Effect of particle size and heating rate on the pyrolysis of Silopi asphaltite Altun, Naci Emre; Kök, Mustafa Verşan (Elsevier BV, 2003-5) This study comprises the effect of particle size and heating rate on the pyrolysis of Silopi, Turkey asphaltite by non-isothermal thermogravimetry. The TG/DTG experiments were performed at five different heating rates with three different size fractions from ambient up to 900 degreesC in nitrogen atmosphere. The pyrolysis characteristics of the samples were analyzed using TG/DTG curves. Also, the pyrolysis kinetics of the samples were determined using the Arrhenius type kinetic model and ASTM methods. Resul...
