Abstract
This work presents a novel zero in-plane Poisson's ratio honeycomb
design for large out-of-plane deformations and morphing. The novel
honeycomb topology is composed by two parts that provide separate
in-plane and out-of-plane deformations contributions. The hexagonal
component generates the out-of-plane load-bearing compression and
in-plane compliance, while a thin plate part that connects the hexagonal
section delivers the out-of-plane flexibility. The paper illustrates
the in-plane mechanical properties through a combination of theoretical
analysis, FE homogenization and experimental tests. Parametric analyses
are also carried out to determine the dependence of the in-plane
stiffness versus the geometric parameters that define the zero-ν honeycomb.
