Best strategy to implement an induced stress (thermal/chemical/...)

Here is a problem I am faced with : I am studying a smart material that, when stimulated by external stimulus, will change shape. So the induced strain is given by an internal stress :
sigma(x) = E*(eps-eps_ind(x))
where E is the Young modulus / eps is the strain coming from a mechanical deformation / eps_ind is the strain induced in the material
The eps_ind(x) could represent different things, depending on the physics studied.
My question is the following : what could be the best strategy to implement it under the Solid Mechanics module under Comsol4.x ?

I'm not sure for how to implement that one, but one thing: be aware that "eps" is an internally defined variable COMSOL name, so you should at least call it something else

Good luck
