The magneto-elastic instability of Kirchhoff rings

Abstract Understanding the interplay between electromagnetic forces and elasticity is a fundamental problem in the mechanics of deformable structures, particularly when electrical currents interact with magnetic fields to generate distributed body forces. A paradigm for this prob...

Nematic bubbles and the breaking of spherical symmetry

Abstract The emergence of nematic order on deformable closed surfaces plays a pivotal role in the morphogenesis of active biological matter, such as the regeneration of Hydra. In this work, we present a continuum model that couples the two-dimensional (2D) Landau–de Gennes order...
