Non-linear progressive failure analysis of open-hole composite laminates under combined loading
Gunel, Murat; Kayran, Altan (SAGE Publications, 2013-05-01)
This article presents a finite element-based study of geometrically non-linear progressive failure analysis of open-hole composite laminates, subjected to combined in-plane and out-of-plane loading. Different ply- and constituent-based failure criteria and material property degradation schemes have been coded in Patran command language and a progressive failure analysis code is developed. Progressive failure analyses of the sample composite laminate, with an open-hole, subject to different combined loading ...
Non-fickian moisture absorption in polymers coated with a thin nanocomposite layer
Altan, Altan; Altan, M. Cengiz; Guloglu, GÖRKEM EĞEMEN; Güloğlu, Görkem Eğemen (2014-01-01)
Moisture absorption in polymers and polymeric composites is well known to lead to significant degradation in mechanical properties. Most epoxy based composites may absorb 2 to 5 wt.% moisture when they are subjected to humid environments. Moisture absorption in polymers has been often characterized with Fickian or various non-Fickian models to describe the time-dependent absorption phenomena. Previous experiments have shown that dispersing moderate amounts of nanoclay in an epoxy resin can: (i) reduce the t...
Nonradiative energy transfer in colloidal CdSe nanoplatelet films
Guzelturk, Burak; Olutas, Murat; Delikanli, Savas; Keleştemur, Yusuf; Erdem, Onur; Demir, Hilmi Volkan (2015-01-01)
Nonradiative energy transfer (NRET) has been extensively studied in colloidal nanocrystal (quantum dots) and nanorod (quantum wires) assemblies. In this work, we present the first account of spectroscopic evidence of NRET in solid thin films of CdSe based colloidal nanoplatelets (NPLs), also known as colloidal quantum wells. The NRET was investigated as a function of the concentration of two NPL populations with different vertical thicknesses via steady state and time resolved spectroscopy. NRET takes place...
Non-convex rate dependent strain gradient crystal plasticity and deformation patterning
Yalçınkaya, Tuncay; Geers, M.G.D. (2012-09-15)
A rate dependent strain gradient crystal plasticity framework is presented where the displacement and the plastic slip fields are considered as primary variables. These coupled fields are determined on a global level by solving simultaneously the linear momentum balance and the slip evolution equation, which is derived in a thermodynamically consistent manner. The formulation is based on the 1D theory presented in Yalcinkaya et al. (2011), where the patterning of plastic slip is obtained in a system with no...
