Void growth based inter-granular ductile fracture in strain gradient polycrystalline plasticity
Tandogan, I. T.; Yalçınkaya, Tuncay; Ozdemir, I (2021-12-01)
The precipitation hardened, high strength aerospace alloys (e.g. Al 7000 alloy series) suffer from loss of fracture toughness due to the heat treatment leading to intergranular ductile fracture. Depending on the quenching and aging processes, large precipitates at the grain boundaries with wide precipitate free zones might develop. Therefore the grain boundaries constitute a potential location for micro void formation and evolution under the effect of external loads. This is a common problem of such materia...
Stress Scaling Factors for Seismic Soil Liquefaction Engineering Problems: A Performance-Based Approach
Çetin, Kemal Önder; Bilge, Habib Tolga (2013-06-19)
Most of the widely used seismic soil liquefaction triggering methods propose cyclic resistance ratio (CRR) values valid at the reference normal effective stress (sigma(v,0)') of one atmosphere and zero static shear stress (tau(st,0)) states. Then, a series of correction factors are applied on this reference CRR, for the purpose of assessing the variability due to normal effective and static shear stress states (i.e. K-sigma and K-alpha corrections) acting on the horizontal plane. In the literature, a number...
Void intergranual motion under the action of electromigration forces in thin film interconnects with bamboo structure
Oren, EE; Ogurtani, TO (2001-11-30)
The rigorous formulation of the internal entropy production, and the generalized forces and conjugate fluxes associated with the virtual displacement of a triple junction are presented in multi-component systems. Extensive computer simulations are performed on the void configurational evolution during the intergranual motion; under the actions of capillary and electromigration forces in thin film metallic interconnects with bamboo structure having various grain textures, The texture studies in this work sho...
Discharge estimations with regression analysis using basin parameters and gis techniques
Pekpınarlı, Hakan; Usul, Nurünnisa; Department of Geodetic and Geographical Information Technologies (2005)
Discharge estimations at certain cross sections of streams are very important for hydrologic studies especially for designs. In this study, it is aimed to determine regional mathematical equations that represent annual and monthly average discharges at desired locations using basin characteristics obtained with Geographical Information Systems (GIS) techniques and regression analysis. Study area covers three river basins, which are Gediz, Küçük Menderes and Büyük Menderes. The data used are Digital Elevatio...
