“…Olympio and Gandhi (2007, 2010) proposed such a geometry, called accordion design, as a core for morphing skins as shown in Figure 1(a). Based on accordion topology, several other designs have been proposed that mostly differ in the inclined rib’s geometry such as Figure 1(b) and (c) (Bubert et al, 2010; Chen and Fu, 2018; Huang et al, 2016; Liu et al, 2013; Rong and Zhou, 2017; Zou and Zhou, 2017). Chen et al (2015) investigated in-plane mechanical properties of three different ZPR accordion structures with hexagonal, re-entrant, and V-shaped ribs.…”
