| Outline of Final Research Achievements |
In this study, we performed finite element analysis of swelling-induced pattern transformation of gel films with a square lattice of holes, to simulate diamond plate patterns observed in experiments and then to explain the mechanism and the dependence on prestrains. We used an inhomogeneous field theory for polymeric gels in finite element analysis. It was found that buckling to form diamond plate patterns starts locally and then propagates until homogeneous transformation is achieved. It was further found that prestrains in tension delays the onset of pattern transformation and different patterns appear as transitional states during the transformation.
