Can a transverse load with zero resultant buckle an elastic rod like an axial load? Theory, simulations, and experiments show that it can, producing Euler-type instability and postbuckling even in the vanishing-thickness limit.

Dear Colleagues,
I invite you to read our recent paper on hierarchically architected foams published in Extreme Mechanics Letters: Read full article here.
Abstract
May a double restabilization of the trivial path occurr at monotonically increasing compression force?
May movable constraints be exploited to attain target force–displacement curves?
We provide a positive answer to both of these questions in our paper: Koutsogiannakis, Bigoni, Dal Corso. Double restabilization and design of force-displacement response of the extensible elastica with movable constraints, European Journal of Mechanics - A/Solids (2022)

A general class of implicit bodies was proposed to describe elastic response of solids, which contains the Cauchy–Green tensor as a function of Cauchy stress. Here, we consider the buckling of solids described by such a subclass of implicit constitutive relation. We present a general linear incremental theory and carry out bifurcation analysis of a uniaxially compressed rectangular layer described by an implicit constitution. We then provide general governing equations regarding the mixed unknowns, i.e., displacement and stress fields, within the framework of finite strain deformation.
We present a theory for finite and spatial elastic deformation of rods under the influence of arbitrary magnetic field and boundary condition. The rod is modeled as a Kirchhoff rod and is assumed to have uniformly distributed array of uniaxial spheroidal paramagnetic inclusions embedded in it all pointing in the same direction in the undeformed state. The governing equations of the magnetoelastic rod are derived which are further non-dimensionalized and linearized to investigate buckling in such rods.
