Abstract

A constitutive model is developed for the elastic behavior of a thermo-responsive gel subjected to swelling in a water bath to which hydrostatic pressure is applied. Material constants are found by fitting experimental data on poly(N-isopropylacrylamide) gel under unconstrained swelling. Good agreement is demonstrated between the observations and results of simulation. The effects of temperature and pressure on equilibrium water uptake are studied numerically.
