Over the course of this grant we performed mechanical experiments designed to uncover fundamental relations between materials and geometry in light-weight structures created from thin polymer films. Our work has lead to new understanding of the role of defects in bent structures, how fluids can deform thin solids and how the strength of crumpled films can be understood. The latter point will be of considerable importance, because we have supplied quantitative structure property relations for crumpled matter for the first time. Such relations are a necessary prerequisite for their use in real world applications.
