DING and GUO [16] coupled metallurgical principles with the CA method to predict the microstructural evolution and the flow stress of copper under kinds of working conditions......
constants (i.e. α, n, Q and A). Consequently, the flow stress curves predicted by the developed modeling show a good agreement with the corrected ones, which indicates that the developed constitutive modeling could give an accurate and precise prediction for the flow stress of 2099 alloy. Key words: 2099 alloy; constitutive modeling; compensation of strain; flow stress 1 Introduction Aluminum......

Nevertheless, obtaining accurate constitutive models that well describe the flow stress and strain is the key for accurate simulation calculations... traditional constitutive models [13-18]. Among them, LIN et al [13] revised the Johnson-Cook (JC) model to predict the elevated temperature flow stress of high strength alloy steels. The improved......
secondary flow and maximum velocity. Booij [2] using large eddy simulation (LES) simulated flow field in a 180° bend and measured Reynolds shear stress. Vaghefi et al [3] studied experimentally the effect of streamlines variations, the maximum velocity distribution, and the secondary flow strength on bed shear stress distribution along a 180° sharp bend. Naji et al [4] experimentally......
