The aim of the study is to evaluate the performance of three recent yield criteria namely; BBC2008-8p, Yld2003-8p, Hu2003 through the simulation of the hemispherical, cylindrical and square cup drawing processes by comparing the results with the ones obtained by using the von Mises criterion for the isotropic, kinematic and combined hardening and the Hill'48 criterion. For this purpose, two different sheet materials, SS304 stainless steel and DKP6112 steel, and various punch travels were used in the simulations and experimental phases of this study. The BBC2008-8p, Yld2003-8p and Hu2003 models were implemented to the ABAQUS software through the user material subroutine VUMAT. The thickness strain distributions obtained from the simulations were compared with the experimental results to analyze the validity of the three aforementioned criteria. Compared with the other models, the material behavior in deep drawing cases of this study is better predicted with more recent models, namely BBC2008-8p, Yld2003-8p and Hu2003, which include anisotropy parameters found from uniaxial and biaxial tension tests.

A SURVEY OF FATIGUE CRACK-GROWTH LIFE ESTIMATION METHODOLOGIES AKYUREK, T; BILIR, OG (Elsevier BV, 1992-07-01) In this study, three fatigue crack growth life estimation methodologies are reviewed and sample calculations are made using these methodologies. Comparisons of the results with respect to the methodologies are made. Three computer codes which represent these methodologies, CRACKS IV, FAST and FATIGUE, are selected for the analyses. The estimations are also correlated to the test results.
Comparison of homogeneity tests for temperature using a simulation study Yozgatlıgil, Ceylan (Wiley, 2016-01-01) Homogeneity testing is one of the most important analyses in climate-related studies as it underpins the reliability of any inferences. The effects not directly related with climate are identified and removed from the meteorological variables, and then the obtained homogeneous variables are used to present an enhanced picture of the current situation and produce realistic forecasts based upon the variables. In this study, we investigate the performances of well-known homogeneity tests and introduce some tes...
Evaluation of environmental parameters in logistic regression models for landslide susceptibility mapping Süzen, Mehmet Lütfi (Informa UK Limited, 2012-01-01) The aim of this study was to determine how well the landslide susceptibility parameters, obtained by data-dependent statistical models, matched with the parameters used in the literature. In order to achieve this goal, 20 different environmental parameters were mapped in a well-studied landslide-prone area, the Asarsuyu catchment in northwest Turkey. A total of 4400 seed cells were generated from 47 different landslides and merged with different attributes of 20 different environmental causative variables i...
Estimation of seismic losses in urban regions within an interdisciplinary framework a case study Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet; Asten, Michael; Karim Zadeh Naghshineh, Shaghayegh (2014-04-30) Abstract – The purpose of the study described in this article was to assess teachers’planning practices at the primary-school level in Turkey. Altogether 210 schools weresurveyed, a questionnaire was distributed to all teachers in these schools, and 1194teachers responded to the questionnaire. The results indicated that the main sourcesof influence on daily and unit plans are teachers’ experience, the national curriculumand the course textbooks. In daily planning, teachers ass...
A phase diagram for ammonium halides Yurtseven, Hasan Hamit; Tublek, A (Informa UK Limited, 1995-01-01) In this study we have developed a mean field model to obtain the phase diagrams for NH4Cl and NH4Br. The phase diagrams obtained from our macroscopic theory are in good agreement with those obtained experimentally.
