Fractal features of a crumpling network in randomly folded thin matter and mechanics of sheet crushing

Phys Rev E Stat Nonlin Soft Matter Phys. 2013 May;87(5):052806. doi: 10.1103/PhysRevE.87.052806. Epub 2013 May 20.


We study the static and dynamic properties of networks of crumpled creases formed in hand crushed sheets of paper. The fractal dimensionalities of crumpling networks in the unfolded (flat) and folded configurations are determined. Some other noteworthy features of crumpling networks are established. The physical implications of these findings are discussed. Specifically, we state that self-avoiding interactions introduce a characteristic length scale of sheet crumpling. A framework to model the crumpling phenomena is suggested. Mechanics of sheet crushing under external confinement is developed. The effect of compaction geometry on the crushing mechanics is revealed.
