Everyone has crumpled a sheet of paper at some point in their lives, either in frustration or to toss it in the office trash. Squeezed in your hands, it clearly becomes “stiffer” as it is compressed. In this issue of Matter, Xia et al. explore the compressive stiffness and strength of crumpled sheets and probe the effect of adhesion, exploring the effect of complex dimensionality on material properties.

褶皱的床单、分形维数和研究中的皱纹

每个人都曾在生活中的某个时刻弄皱过一张纸，要么是沮丧，要么是把它扔进办公室的垃圾箱。在你的手中挤压，它在被压缩时显然变得“更硬”。在本期《物质》中，夏等人。探索压皱板的抗压刚度和强度，探索粘附的影响，探索复杂尺寸对材料性能的影响。
