초록

Restoration behavior of folded Korea bank note was studied. The variables were folding radii (0.5, 1, 3, 5. 7, 9 mm) and folding time. Initially, bank note was completely folded to make $180^{\circ}$ against predetermined radius panel, and restored angles were measured according to allowed restoration time. We found as folding radius was smaller and as folding time was longer, restoration speed of folding angle became slower and the amount of final restoration was smaller, respectively. Initial restoration angles were related to the elastic moduli of the bank notes, and final restoration angles were inversely related to the TEA of the bank notes, respectively.
