What's the meaning of "the maximum dissipation principle"?
Hi everyone
I am a graduate student.I am trying to formulate a constitutive equation for rock salt based on irreversible thermodynamics theory. Recently,I encounted two prolems:
(1)how to define the damage variable?
(2)what's the meaning of "the maximum dissipation principle"?
could everyone give me some advice?
thanks a lot.
