PhD candidate Michael Buche and Prof. Silberstein just published a paper on the constitutive modeling of polymer networks using statistical mechanics in Physical Review E. This work is the first to accomplish a general derivation that starts from arbitrary non-interacting single-chain behaviors and ends in the Cauchy stress. It highlights the naturally-occurring statistical correspondences that have been traditionally ignored, and investigates their effects on the macroscopic mechanical response of the network. Our approach here is vital for future constitutive model development.
