The aim of the study is to find out the effects of different models namely; BBC2008-8p, Yld2003-8p, Hu2003, isotropic hardening, kinematic hardening, combined hardening and Hill’48 on simulation of cylindrical, square and round bottom cup drawing processes. For this purpose two different sheet materials, SS304 stainless steel and DKP6112 steel with 1 mm thickness and three different punch travels were used in both computer simulation and experimental phase of this study. BBC2008-8p, Yld2003-8p and Hu2003 models were implemented to the software with the user material subroutine. The thickness strain distributions obtained by simulations for the seven models were compared with the experimental findings to find out their consistency. It is found that the implemented recent models namely, BBC2008-8p, Yld2003-8p and Hu2003 models are better to predict the material behavior in deep drawing cases presented in the study .

USE OF A SOCIAL COGNITIVE THEORY-BASED PHYSICAL-ACTIVITY INTERVENTION ON HEALTH-PROMOTING BEHAVIORS OF UNIVERSITY STUDENTS
İnce, Mustafa Levent (SAGE Publications, 2008-12-01)
The purpose of this study was to examine the effects of a 12-wk. physical activity intervention, based on conceptual discussions and practices of a social cognitive theory on health-promoting behaviors of 62 university students. The intervention Mainly focused on development of self-regulatory skills, social support, and self-assessment of health-related fitness. The Adolescent Health Promotion Scale and International Physical Activity Questionnaire were given Analysis of self-reports indicated improved nut...
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...
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...
The effect of strain rate and temperature on deep drawing for different constitutive relations
Gökşen, Seçkin; Darendeliler, Haluk; Department of Mechanical Engineering (2019)
In this study, the effects of strain rate and temperature on deep drawing process are investigated by considering different yield criteria and hardening models. For this purpose, various punch velocity and temperature values are considered using 1 mmthick DKP6112 and AZ31 sheet materials. The results are compared according to thickness strain distribution and punch force obtained by a commercial finite element software. To express constitutive relations of corresponding materials for different strain rate a...
A comparison of orthogonal cutting data from experiments with three different finite element models
Bil, H; Kilic, SE; Tekkaya, AE (Elsevier BV, 2004-07-01)
The aim of this study is to compare various simulation models of orthogonal cutting process with each other as well as with the results of various experiments. Commercial implicit finite element codes MSC.Marc, Deform2D and the explicit code Thirdwave AdvantEdge have been used. In simulations, a rigid tool is advanced incrementally into the deformable workpiece which is remeshed whenever needed. In simulations with MSC.Marc and Thirdwave AdvantEdge, there is no separation criterion defined since chip format...
