Three-dimensional continuous curvature design based on spatio-temporal stress analysis on locally actuated shape morphing polymer film by thermal stimulus |
| 초록 |
Three-dimensional (3D) curvature morphing based on two-dimensional (2D) shape memory polymer (SMP) has received great attention due to its curvature reconfiguration property. In terms of designing the intended 3D configuration, the analysis of the stress convolution effect which causes the shape morphing should be preceded. In this study, the 3D curvature morphing of bi-axially pre-strained polystyrene (PS) film actuated by the thermal stimulus is computationally modeled for performing the spatio-temporal simulation. When the locally patterned area on PS film is actuated, the stress convolution effect between patterned and non-patterned areas occurs resulting in 3D reconfiguration. Finally, the curvature morphing process with the final 3D configuration is predicted by spatio-temporal simulation.
