Semisolid metallurgy
 
Hi, I am a beginner
I am trying to model a semisolid behaviour ( thixotropic) using the Carreu equation to do it, but I cannot adapt my model to it, because my model is like:
viscosity=c1*T^(c2)*shear rate^(c3) ,
where c1, c2, c3 are constant parameters. The problem is that in the carreu model Temperature is the argument of an exponential, so my model does not fit in the Carreu.

I also tried to learn customization, but it is so difficult.

If you could give me any help (Examples, explanations...) I would be very grateful.
