behzad is still having a problem:
Hi,

the new constitutive law I need to implement is that of Burger's model.
This model is composed of a Kelvin model (dashpot in parallel of a
spring) in series of a Maxwell model (dashpot in series with a spring).
Thus, it has four parameters; two viscosity of the dashpots and two
stiffness for two springs.

The deformation equation of this model is given by;

I don't know how should I start writing this in C++ for yade!

cheers,
Behzad
