Computational analysis on programmable shape-morphing of bi-axially pre-strained glassy polymer actuated by local heating effect |
| 초록 |
Shape-morphing of shape memory polymer (SMP) from two-dimensional (2D) to three-dimensional (3D) has received great attention because of the ability to design its shape reconfiguration. In addition, for the design to get the intended shape, the analysis of the stress distribution that causes the shape morphing should be preceded. In this study, we carried out computational analysis about 3D shape morphing of bi-axially pre-strained polystyrene (PS) film actuated by local heating effect. When the temperature of pattern area exceed over glass transition temperature (Tg) of PS film, pre-strained PS film was contracted with causing the stress in entire film area. We derived the shape morphing process with the final 3D shape from computational analysis about stress distribution in PS film. Furthermore, we also applied the transmittance map of the morphed PS film about polarized light for getting the more precise analysis about shape morphing. |
