Modelling of the crumpling process of a paper sheet
23rd International Conference on Graphic Engineering, Madrid
The packaging sector needs innovative solutions to face both the worldwide competitiveness between companies and sustainable development issues. In response to this demand, this paper proposes the study of a new folding technique which erects 3D structures from a single flexible sheet. This technique consists in creating a network of complex patterns according to a crumpling process that generates random folds. In order to give a better understanding on the crumpling process, a descriptive modelling is proposed. It highlights useful and useless characteristics conferred to a flexible sheet and gives ways for the development of graph based methods more adapted to the modelling of crumpled structures. A study case on a food packaging supports the proposition.
