“…Spigarelli et al [ 1 ] analyzed the peak stress dependence on strain rate and temperature based on a series of torsion tests in a wide range of temperatures and strain rates. With regard to the 6082 aluminum mechanical properties, several fruitful studies were conducted, such as Tranə et al [ 2 ], who have evaluated the drawing efficiency of 6082 0 temper aluminum alloy for cartridge tubes. They applied the Piecewise-Linear-Plasticity constitutive model and the Cockcroft-Latham fracture criterion to the simulations.…”

This study aims to investigate the flow and fracture behavior of aluminum alloy 6082-T6 (AA6082-T6) at different strain rates and triaxialities. Two groups of Charpy impact tests were carried out to further investigate its dynamic impact fracture property. A series of tensile tests and numerical simulations based on finite element analysis (FEA) were performed. Experimental data on smooth specimens under various strain rates ranging from 0.0001~3400 s-1 shows that AA6082-T6 is rather insensitive to strain rates in general. However, clear rate sensitivity was observed in the range of 0.001~1 s-1 while such a characteristic is counteracted by the adiabatic heating of specimens under high strain rates. A Johnson-Cook constitutive model was proposed based on tensile tests at different strain rates. In this study, the average stress triaxiality and equivalent plastic strain at facture obtained from numerical simulations were used for the calibration of J-C fracture model. Both of the J-C constitutive model and fracture model were employed in numerical simulations and the results was compared with experimental results. The calibrated J-C fracture model exhibits higher accuracy than the J-C fracture model obtained by the common method in predicting the fracture behavior of AA6082-T6. Finally, the Scanning Electron Microscope (SEM) of fractured specimens with different initial stress triaxialities were analyzed. The magnified fractographs indicate that high initial stress triaxiality likely results in dimple fracture.

ÖZBu çalışmada, sonlu elemanlar analizi kullanılarak, sabit mandrel ile soğuk boru çekme işleminin benzetimi yapılmış olup, kesit daralma oranının, yarı kalıp açısının, yarı mandrel açısının ve sürtünme katsayılarının çekme gerilmesine etkileri araştırılmıştır. Sonlu elemenlar modeli, %16 kesit daralmasındaki deneysel verilerle doğrulanmıştır. Netice olarak, yarı kalıp açısının plastik şekil değişimine etkisi yarı mandrel açısından daha büyük olmuştur. Sebebi ise kalıp açısının büyüklüğünden kaynaklanmaktadır. 12 o 'lik yarı kalıp açısı bütün sürtünme değerleri için minumum çekme gerilmesini vermektedir. Sabit konik mandrel ile boru çekme işleminde 7 o 'lik yarı kalıp açısı için 2-4 o aralığındaki yarı mandrel açısı kullanılmalıdır. Deneysel ve sonlu elemanlar analiz sonuçlarının uyum içinde olduğu görülmüştür.Anahtar Kelimeler: Soğuk boru çekme, Sonlu eleman analizi (FEA), çekme gerilmesi, yarı kalıp açısı, yarı mandrel açısı Effect of the process parameters on cold tube drawing with a fixed plug using finite element analysis for AISI 1010 steel ABSTRACTIn this present work, finite element analysis (FEA) is applied to simulate cold tube drawing process with a fixed plug for AISI 1010 steel tube. The effects of reduction of area, semi die angle, semi plug angle, and friction coefficient on drawing stress are studied. The finite element model is successfully validated with the experimental data at reduction of area 16%. Results indicate that a good agreement between the experimental and the finite element analysis (FEA) is found. Consequently, the effect of semi die angle on plastic deformation is larger than the semi plug angle because of the bigger size of the semi die angle. Semi die angle of 12° gives minimum drawing stress for all coefficient of frictions. A semi plug angle between 2° and 4° should be used in tube drawing process with a conical fixed plug when semi die angle is equal to 7 o .
