WebIn this paper, we model the photomechanics of light-activated, network rearranging polymers subjected to simultaneous deformation and network evolution. We then apply the model to the case of photo-induced creep behavior where a constant force is applied to the material during light irradiation. Note that photo-induced creep behavior yields WebA photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
