Much recent progress has been made in the study of nematic solids, both glassy and elastomeric, particularly in the realm of stress-free, defect-driven deformation in thin sheets of material. In this paper we consider a subset of texture domains in nematic glasses that are simple to synthesize, and explore the ways that these simple domains may be compatibly combined to yield analogs of the traditional smooth disclination defect textures seen in standard liquid crystals. We calculate the deformation properties of these constructed textures, and show that, subject to the compatibility constraints of the construction, these textures may be further combined to achieve shape blueprinting of three-dimensional structures from flat sheets.
最近在向列型固体(包括玻璃态和弹性体)的研究方面取得了很大进展,特别是在无应力、缺陷驱动的薄片材料变形领域。在本文中,我们考虑了向列型玻璃中易于合成的纹理域子集,并探索了如何将这些简单域进行兼容组合,以产生在标准液晶中看到的传统光滑位错缺陷纹理的类似物。我们计算了这些构造纹理的变形特性,并表明,在构造的兼容性约束下,这些纹理可以进一步组合,以实现从平板到三维结构的形状蓝图。
