Jan Stránský proposed the following answer:
Hello,

I think what you require is impossible.

All the three quantities (stress, unbalanced force, porosity) are not independent.
fixed porosity: higher unbalanced force -> higher stress
fixed unbalanced force: lower porosity -> higher stress
fixed stress: higher unbalanced force -> lower porosity
So you cannot fix both stress and porosity and let unbalanced force disappear...

cheers
Jan
