Variational derivation of the Flamant solution for a nonlinear elastic wedge
Dominik Engl, Paul Plucinsky, Ian Tobasco
Concentrated forces acting at the tip of a two-dimensional wedge give rise to the classical Flamant solution to linear elasticity, whose displacement and strain are singular at the…
Mechanism-based metamaterials with microstructurally invariant shape-change
Yingchao Peng, Asifur Rahman, Paolo Celli +1
Metamaterials with floppy modes called mechanisms are a burgeoning template for shape-morphing systems and structures across scales. Here, we present a design recipe that transform…
Modeling and computation of the effective elastic behavior of parallelogram origami metamaterials
Hu Xu, Frederic Marazzato, Paul Plucinsky
Origami metamaterials made of repeating unit cells of parallelogram panels joined at folds dramatically change their shape through a collective motion of their cells. Here we devel…
Derivation of an effective plate theory for parallelogram origami from bar and hinge elasticity
Hu Xu, Ian Tobasco, Paul Plucinsky
Periodic origami patterns made with repeating unit cells of creases and panels bend and twist in complex ways. In principle, such soft modes of deformation admit a simplified asymp…
