Buckling Collapse Strength of Chip Carrier under Longitudinal Bending (1st Report)

Elastocapillary instability under partial wetting conditions: bending versus buckling.

The elastocapillary instability of a flexible plate plunged in a liquid bath is analyzed theoretically. We show that the plate can bend due to two separate destabilizing mechanisms, when the liquid is partially wetting the solid. For contact angles θ(e) > π/2, the capillary forces acting tangential to the surface are compressing the plate and can induce a classical buckling instability. However...

The strength of PIN–PMN–PT single crystals under bending with a longitudinal electric field

The effect of an electric field on the bending behavior of [001] oriented and poled relaxor Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 (PIN–PMN–PT) single crystals was measured using a four point bending apparatus with a longitudinal electric field applied to the bar during bending. The surface finish and electric field amplitude were observed to affect the bending strength. Polished surfaces imp...

Experimental Investigations into the Collapse of Simple and Reinforced Thin-Walled Channel Beams under Bending Loads

In this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. Many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. Since the available theories in this area are complicated and little attention has been paid to...
