Abstract: Snap-through of buckled beams or shallow arches may be utilized in some MEMS devices. Such behavior can be induced by applied moments at the ends. A simply-supported uniform shallow elastic ...

Abstract: Lateral bracing requirements for two‐span elastic columns are examined. The braces are represented by elastic translational springs. The columns have pinned supports at the base, an internal brace at an arbitrary point, ...

Abstract: The snap-through instability of a uniform, shallow, elastic arch is considered. The arch has a sinusoidal shape and is subjected to a uniformly distributed load. As the load is increased, the flexural resistance of the ...

Abstract: A structure consisting of two arches leaning against each other and attached at their crowns is considered. Such structural units are used in bridges and in frameworks for tents. Their three-dimensional elastic behavior ...

Abstract: Buckling of rectangular plates under uniaxial loading is considered. The plates are uniform and elastic, and the load is uniform. The unloaded edges are simply supported, whereas the loaded edges have no out‐of‐plane ...

Abstract: Elastic columns with two spans of arbitrary length ratio are investigated. The base is pinned and may include a rotational spring. An elastic support acts between the spans, and the top is pinned or supported elastically. ...

Abstract: A pinned column with an initial deflection and an internal brace is considered. The brace is modeled as a translational spring. Axial compressive loads are applied at the brace and at the top of the column, and the equilibrium ...

Abstract: The behavior of uniform, elastic, braced columns with three spans is investigated. The spans may have equal or unequal lengths. The base of the column is pinned and the top is either pinned or flexibly supported. The braces ...

Abstract: Vibration frequency measurements are sometimes used to nondestructively predict buckling loads. Various powers of the fundamental frequency may be plotted as a function of the load. A curve-fitting procedure may be applied ...
