We present an analytical framework to describe the complex nonlinear responseof two-dimensional porous mechanical metamaterials. We adopt a geometricapproach to elasticity in which pores are represented by elastic charges, andshow that this method captures with high level of accuracy both the shapedeformation of individual pores as well as collective deformation patternsresulting from interactions between neighboring pores. Specifically, we showthat quadrupoles and hexadecapoles - the two lowest order multipoles availablein elasticity - are capable of matching the experimentally observed evolutionin shape and relative orientation of the holes in a variety of periodic porousmechanical metamaterials. Our work demonstrates the ability of elastic chargesto capture the physics of highly deformable porous solids and paves the way tothe development of new theoretical frameworks for the description and rationaldesign of porous mechanical metamaterials.
