Abstract
Miura-Ori based foldcores have been regarded asa potential substitute for conventional honeycomb cores due to many advantages, such as open structure and continuous manufacturing process. Arc-Miura foldcore is one of the Miura-derivative cores which does not have curvature limitations. In this research, the arc-Miura specimens were successfully manufactured using a stamping process and tested under a quasi-static out-of-plane compressive load. An explicit finite element analysis (FEA) of arc-Miura models was developed and validated with the experimental results. Furthermore, a parametric study of arc-Miura models subjected to quasi-static out-of-plane compression was performed, through which the relationships between the mechanical properties and the geometric parameters were established. Finally, the mechanical properties of arc-Miura models and corresponding monolithic arches were compared. It was shown that arc-Miura patterns perform better than the corresponding monolithic arches in terms of force and energy absorption.
