Sandwich structures with Miura-ori cores have been studied in aerospace industry, but this study focuses on the mechanical performance of planar, self-supporting Miura-ori structures under compressive loads. By analyzing the effects of geometric parameters and material orthotropy, the study provides a basis for structural design.
Sandwich structures with Miura-ori cores have been studied especially in aerospace industry. However, by removing the face sheets one can obtain esthetical, multifunctional, self-supporting structures for various applications, such as packaging. This study focuses on the mechanical performance of planar, self-supporting Miura-ori structures under compressive loads. Through systematic variations of both origami geometry and base material orientation, this study performs linear stress and stability analyses by utilizing the finite element method. The results reveal the effects of the geometric parameters and the material orthotropy on the structural performance, finally resulting in parameter ranges forming a basis for structural design.
