Writing UHYPER for photo-thermal sensitive hydrogels described in the thermodynamic framework?
Hello
I`d like to write a UHYPER for photo-thermal sensitive hydrogels described in the thermodynamic framework. But the photo-chemical term in the energy equation is 7order greater than the others. The other terms are related to stretch and mixing energy they exist also in the temperature sensitive hydrogels energy equations and their UHYPER is valid. I have checked all the coefficients, their orders are all correct.
Is it something wrong with modeling, or I have made a mistake?
