...Danny Smyl Significant research effort has been devoted to topology optimization (TO) of two- and three-dimensional structural elements subject to various design and loading criteria. While the field of TO has been tremendously successful over the years, literature focusing on the optimization...

... a physical element to fit this assumption, a curved leaf spring is used. From the previous research [ 39 ], it was found that this is one of the only possibilities if a planar and monolithic structure is required. This research describes the spring shape being obtained using an optimization algorithm...

...Wei Ye; Feng Wei; Jin Yi; Zhu Chang'an In this paper, we generalize Miura origami and propose a method for analyzing a generalized Miura origami structure. Morphological properties of the generalized Miura origami element during the deploy motion are analyzed using the proposed method, which mainly...

...Dongping Deng; Tsz-Ho Kwok; Yong Chen Traditional origami structures fold along predefined hinges, and the neighboring facets of the hinges are folded to transform planar surfaces into three-dimensional (3D) shapes. In this study, we present a new self-folding design and fabrication approach...
