Packing of particles in confined environments is a common problem in multiple fields. Here, based on the two-dimensional Hertzian particle model, we study the packing of deformable spherical particles under compression and reveal the crucial role of stress as an ordering field in regulating particle arrangement. Specifically, under increasing compression, the squeezed particles spontaneously organize into regular packings in the sequence of triangular and square lattices, pentagonal tessellation, and the reentrant triangular lattice. The rich ordered patterns and complex structures revealed in this work suggest a fruitful organizational strategy based on the interplay of external stress and intrinsic elastic instability of particle arrays.

应力引起的弹性球二维填料的排序。

密闭环境中的颗粒堆积是多个领域中的常见问题。在此，基于二维赫兹粒子模型，我们研究了压缩下可变形球形粒子的堆积，并揭示了应力作为有序场在调节粒子排列中的关键作用。具体地，在增加的压缩下，被挤压的颗粒自发地组织成规则堆积，这些堆积为三角形和正方形格子，五边形细分和凹角三角形格子的序列。这项工作中揭示的丰富的有序模式和复杂的结构表明，基于外部应力和粒子阵列固有的弹性不稳定性的相互作用，组织策略是卓有成效的。
