Steel Composite

Through the comparative analysis of theoretical and experiment results, this paper proved that the formulas for solving the strain of composite beams are correct, and the strain is consistent with the plane cross-section assumption. In order to reduce the influence of friction, resin membranes were placed in steel-steel composite beams and aluminum-steel composite beams. The strain measurements were performed on composite beams with and without adding resin, the influence of friction between the composite beams is analyzed by the comparison of strain data,.

The subject of this paper is the analysis, by means of an optical-interferometric method, of the displacements of a multiple-shell roof, composed of π-shaped elements, mutually connected by linear hinges. The first part deals with both the warping of the section (due to combined bending and torsion) and plane cross-section deformations: two different theoretical approaches (‘rigid section’ and ‘deformable section’) are considered, so that experimental and theoretical results can be compared; a linear load is applied to each hinge in turn, In the second part, the effects of diaphragm spacing on the section distortion are analysed in the case of a single prismatic element.

Carbon Ions

AbstractThe photoabsorption spectra of the carbon ions have been obtained by using two laser-produced plasmas. The photoionization cross-section of the CV has been absolutely measured and the value at threshold, σ=(4.7±0.5) × 10−19cm2, as well as its behaviour at higher energies agrees quite well with the theoretical calculations.
