A study of molecular orientation in stretched film using SPH method

Abstract

In recent years, the development of flexible materials, such as thin sensors that can be attached to the human body, has attracted much attention. In this study, we focus on the SPH method, which is a kind of mesh-free method, and aim to apply it to the calculation of molecular orientation. We attempted to calculate the orientation using the internal stress of the stretched film. We also investigated the change in molecular orientation when an electric field was applied to the stretched film.
