Query: Effective continuum models for the buckling of non-periodic architected
  sheets that display quasi-mechanism behaviors   In this work, we construct an effective continuum model for architected
sheets that are composed of bulky tiles connected by slender elastic joints.
Due to their mesostructure, these sheets feature quasi-mechanisms -- low-energy
local kinematic modes that are strongly favored over other deformations. In
sheets with non-uniform mesostructure, kinematic incompatibilities arise
between neighboring regions, causing out-of-plane buckling. The effective
continuum model is based on a geometric analysis of the sheets' unit cells and
their energetically favorable modes of deformation. Its major feature is the
construction of a strain energy that penalizes deviations from these preferred
modes of deformation. The effect of non-periodicity is entirely described
through the use of spatially varying geometric parameters in the model. Our
simulations capture the out-of-plane buckling that occurs in non-periodic
specimens and show good agreement with experiments. While we only consider one
class of quasi-mechanisms, our modeling approach could be applied to a diverse
set of shape-morphing systems that are of interest to the mechanics community.
