The most severe imperfection governs the buckling strength of pressurized multi-defect hemispherical shells
Fani Derveni, Florian Choquart, Arefeh Abbasi +2
We perform a probabilistic investigation on the effect of systematically removing imperfections on the buckling behavior of pressurized thin, elastic, hemispherical shells containi…
Probabilistic buckling of imperfect hemispherical shells containing a distribution of defects
Fani Derveni, William Gueissaz, Dong Yan +1
The buckling of spherical shells is plagued by a strong sensitivity to imperfections. Traditionally, imperfect shells tend to be characterized empirically by the knockdown factor,…
Snap buckling of bistable beams under combined mechanical and magnetic loading
Arefeh Abbasi, Tomohiko G. Sano, Dong Yan +1
We investigate the mechanics of bistable, hard-magnetic, elastic beams, combining experiments, finite element modeling (FEM), and a reduced-order theory. The beam is made of a hard…
A reduced-order, rotation-based model for thin hard-magnetic plates
Dong Yan, Bastien F. G. Aymon, Pedro M. Reis
We develop a reduced-order model for thin plates made of hard magnetorheological elastomers (hard-MREs), which are materials composed of hard-magnetic particles embedded in a polym…
A geometrically exact model for thin magneto-elastic shells
Matteo Pezzulla, Dong Yan, Pedro M. Reis
We develop a reduced model for hard-magnetic, thin, linear-elastic shells that can be actuated through an external magnetic field, with geometrically exact strain measures. Assumin…
A comprehensive framework for hard-magnetic beams: reduced-order theory, 3D simulations, and experiments
Dong Yan, Arefeh Abbasi, Pedro M. Reis
Thin beams made of magnetorheological elastomers embedded with hard magnetic particles (hard-MREs) are capable of large deflections under an applied magnetic field. We propose a co…
Magneto-active elastic shells with tunable buckling strength
Dong Yan, Matteo Pezzulla, Lilian Cruveiller +2
Shell buckling is central in many biological structures and advanced functional materials, even if, traditionally, this elastic instability has been regarded as a catastrophic phen…
