Parametric linear finite element stress and stability analysis of isotropic and orthotropic self-supporting Miura-ori structures

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 for various applications, such as packaging. This study focuses on mechanical performance of planar, under compressive loads. Through systematic variations both origami geometry and base material orientation, this performs linear stress stability analyses utilizing finite element method. The results reveal effects geometric parameters orthotropy structural performance, finally resulting parameter ranges forming a basis design.
