一个拼图游戏超材料的概念
A jigsaw puzzle metamaterial concept
摘要:
受自然界局部自适应原理的启发,提出了平面模块化机械超材料的概念。这种超材料由类似于拼图的相同碎片组成。它们在组件内的旋转在结构行为和机械互锁方面提供了相当大的灵活性,从而能够重新组装。具有对角椭圆形开口的瓷砖设计允许我们改变弹性特性-从刚性到顺应性,具有正、零或负泊松比。对增材制造样本的实验测试结果证实,可以使用优化方法并以有限元分析为核心来准确设计装配性能。
英文摘要:
A concept of a planar modular mechanical metamaterial inspired by the nature's principle of local adaptivity is proposed. The metamaterial consists of identical pieces similar to jigsaw puzzle tiles. Their rotation within assembly provides a substantial flexibility in terms of structural behavior and mechanical interlocks enable reassembly. The tile design with a diagonal elliptical opening allows us to vary elastic properties--from stiff to compliant, with positive, zero, or negative Poisson's ratio. The outcomes of experimental testing on additively manufactured specimens confirm that the assembly properties can be accurately designed using optimization approaches with finite element analysis at heart.
