Glassy azopolymers deform in the presence of light even below the glass transitiontemperature. In this work we model the azopolymers in the presence of homogeneousand spatial dependent light intensity for different polarization. The photodeforma-tions are directional and depend on the polarization of light. The cause of thesedirectional deformations is the orientation potential which acts on each chromophoreattached to the main chain and generates a light induced stress.

In this work we model the azopolymers in the presence of homogeneousand spatial dependent light intensity for different polarization. The photodeforma-tions are directional and depend on the polarization of light. The cause of thesedirectional deformations is the orientation potential which acts on each chromophoreattached to the main chain and generates a light induced stress. We model theazopolymers as visco-plastic materials by implementing the stress in a finite elementmodelling software ANSYS. Show less
