在环境压力下起皱
Crumpling under an ambient pressure
摘要：
设计了一个压力室来研究在环境力作用下的折皱过程。球的压缩力及其产生的半径服从幂律，其指数与片材的厚度和初始尺寸无关。然而，指数被发现是材料依赖性的，并且小于之前的模拟所声称的普遍值0.25。在高压下，当压缩率不连续下降时，幂律行为消失，这暗示了堵塞状态。
英文摘要：
A pressure chamber is designed to study the crumpling process under an ambient force. The compression force and its resulting radius for the ball obey a power law with an exponent that is independent of the thickness and initial size of the sheet. However, the exponent is found to be material-dependent and less than the universal value, 0.25, claimed by the previous simulations. The power law behavior disappears at high pressure when the compressibility drops discontinuously, which is suggestive of a jammed state.
