currently, I am working on evaluating the relaxation function of a long concrete slab. I am applying Volterra integral in doing so. In my case, the concrete slab is subjected to combined temperature drop and shrinkage. can we use the obtained combined shrinkage and temperature deformations as the imposed deformations (as input)?
or, how to apply the creep deformations in it?
or, do I have to apply any other method?
please suggest to me any related research paper or any material regarding this issue.

Mehran Shahpari Sir, thank you for the articles. but, I have to focus on the theoretical evaluation of relaxation function. if you are aware of articles regarding such methods if you could please share them. I would appreciate it
