This question may seem like an easy one to answer, but for the 3 and
a half years I've been using mathematica, I can't figure out how to
solve my problem. I am plotting the equation: rsta[sig_]:= (sig/ext)
+ (sig/hp)^(1/np) where rsta and sig are variables, the others constants
(for those curious, this is the Ramberg-Osgood equation relation stress
and strain). Unfortunately, this equation plots strain vs. stress,
not stress vs. strain. Is there a way to get this equation to plot
stress vs. strain? Thanks for any help!!
