Outline of Final Research Achievements

The so-called soft elasticity in the stress-strain diagram of Liquid Crystal Elastomer is one of the phenomena in which the mechanism is unclear. In this study, we discard to calculate directly the complex structural changes inside the material, and instead we consider that the origin of the specific behavior in the stress comes from the changes in the length scale inside the material. By using Finsler geometry model constructed along such considerations, we successfully obtain numerical results which are consistent to the existing experimental data.
