Help plotting and graphing yield strees vs strain rate
I dont have any idea how to plot the equation of yield stress ( which is the limit of the elastic range), modeling with this function: σ y/d = 350[ ( ε _t(subscript) / 210) ^ 0.16 + 1] where : strain rate (s^-1) = 0.00007, 0.0002, 0.05, 0.8, 4.2, 215, 3500 and : Yield Stresss(MPa) = 345, 362, 419, 454, 4... 13 May 2010 20:29
