Shear buckling of sandwich, fiber composite and lattice columns, bearings, and helical springs: Paradox resolved
TL;DR: In this paper, it was shown that the shear stiffness of a column, provided by the core, generally depends on the axial force carried by the skins if that force is not negligible compared to the column stiffness.
Journal ArticleDOI
Sandwich buckling formulas and applicability of standard computational algorithm for finite strain
TL;DR: In this article, Bažant's recent study is physically reinterpreted, with the conclusion that only the Engesser-type theory corresponds to constant shear moduli as obtained by the torsional test of a tube made from the foam.

Stability and finite strain of homogenized structures soft in shear: Sandwich or fiber composites, and layered bodies
TL;DR: In this paper, a variational energy analysis of homogenized soft-in-shear orthotropic composites is presented, along with supporting experimental and numerical results, and the analysis is extended to arbitrary multiaxially loaded homogenised softin-soft-inshear composites, and it is shown that the correct stability theory is associated with a general Doyle-Ericksen finite strain tensor of exponent m depending on the principal stress ratio.

Experimental and numerical investigation on the buckling of 3D printed sandwich structure with lattice core
TL;DR: In this article , the buckling performance of 3D printed lattice sandwich structures is investigated and compared using the selective laser melting (SLM) technique, and the results show that the lattice structure has higher bearing capacity and stronger toughness in the post-buckling stage than the body centered cubic (BCC) and rhombic dodecahedron (DOD).

On the General Theory of Elastic Stability
TL;DR: In this paper, the stability of a straight rod in equilibrium under its own weight, under twisting couples, and when rotating was studied, and a comprehensive theory was not propounded until the problem of the straight strut had been investigated by Euler, that of the circular ring under radial pressure by M. Levy and G. H. Greenhill, and A. G.

Die Grundgleichungen der elastischen Stabilität in allgemeinen Koordinaten und ihre Integration
TL;DR: Ausgehend vom Kraftegleichgewicht stellt Verfasser unter Anwendung des absoluten Differentialkalkuls die GrundgleICHungen der Stabilitatstheorie in beliebigen krummlinigen Koordinaten auf, der Vorteil dieser Ableitung ist der, das zunachst keine Voraussetzungen uber das Formanderungsgesetz gemacht zu werden brauchen and das die G
