Abstract

A novel star-shaped cellular structure with great elastic properties is proposed as candidate for multiple morphing applications. Theoretical derivations and finite element analysis are conducted to study the mechanics of the structure. Results show that the in-plane moduli of the structure can be extremely lower than those of the base material, while the maximum global strains reach, dozens of times, the limit elastic strain of the base material. The proposed structure also exhibits lighter weight, lower in-plane moduli and larger strain ratios than the existing semi-sinusoidal structure, which indicates lower actuation requirements and greater strain capabilities for morphing applications.
