Determination of Friction Coefficient by Employing the Ring Compression Test
The main objective of this research was to investigate the effect of material properties, strain-rate sensitivity, and barreling on the behavior of friction calibration curves. The compression tests were conducted to obtain the necessary material properties for the finite element analysis. A series of ring compression tests were then conducted in order to determine the magnitude of the friction...
متن کاملCloze-Elide Test as an Alternative Test Method: Linking Personality Types to Test Method Performance
More innovative test methods may measure language learners’ test performance more accurately, contributing to much fairer decisions. This study examined Iranian language learners’ performance on cloze-elide test as an innovative, integrative test method. It specifically focused on investigating whether personality types correlated with their performance and whether personality types could predi...
متن کاملdetermination of flow stress and friction factor of aluminum 7075 by inverse analysis
in all engineering applications where solid surfaces slide on each other, friction plays an important role. it becomes even more important, particularly in metal forming processes where the two sliding materials are metallic. among forming processes, forging is an important process, because of improving material structure, mechanical properties and reducing production time. an inverse analysis ...
متن کاملOptimization of Flash, Billet Dimensions and Friction Factor in Closed Die Cold Forging Process
Three important parameters in designing a closed die for forging process are ratio of width to flash thickness, ratio of height to billet diameter and the friction factor. In this paper the influences of these parameters on the required force for the forging and percentage of die filling were investigated. It was found that by controlling the flash dimension, the material loss is reduced and t...
