摘要：
To satisfy the requirements of being used as core of flexible sandwich skins for morphing materials, a 2D chiral cellular structure composed of arc-formed beams is studied. The in-plane elastic properties within the linear elastic range of the structure are studied using the energy method, and verified by finite element analysis and experimental test. Besides, the impact of parameters on the properties is discussed. Finally, the elastic properties of the structure are compared with a V-shaped structure. Excellent agreement is reached between finite element results and theoretical analysis. The structure shows zero Poisson's ratio, considerably low in-plane equivalent moduli and extremely high global-local strain ratios, as well as noteworthy in-plane elastic coupling effects. Compared with the V-shaped structure, the elastic and shear moduli of the structure are in average rate 39.32% and 19.94% lower, and the maximum global-local strain ratios under tensile and shear loading are in average rate 62.97% and 24.04% higher. To have better performance in elastic constants, structures with large central angle of the arc are recommended.
