Biologically inspired pressure actuated cellular structures can alter theirshape through pressure variations. Previous work introduced a computationalframework for pressure actuated cellular structures which was limited to twocell rows and central cell corner hinges. This article rigorously extends theseresults by taking into account an arbitrary number of cell rows, a morecomplicated cell kinematics that includes hinge eccentricities and varying sidelengths as well as rotational and axial cell side springs. The nonlineareffects of arbitrary cell deformations are fully considered. Furthermore, theoptimization is considerably improved by using a second-order approach. Thepresented framework enables the design of compliant pressure actuated cellularstructures that can change their form from one shape to another within a set ofone-dimensional C1 continuous functions.
