The use of pipe flange connections is standardized in the codes of JIS, ASME, DIN and so on. However, these codes are almost entirely dependent on experience, and subsequently some problems concerning pipe flange connections have been encountered. In the present paper, the distribution of contact stresses which governs the sealing performance is analyzed as a three-body contact problem, using a...

A prestressing procedure is proposed for reduction of stress concentrations at the leading edges of adhesive bondlines in composite skin/ ange assemblies. A Ž niteelementanalysisof a speciŽ c geometryof such an assembly is presented,whichaccounts for nonlinear viscoelastic deformation of the adhesive. Design diagrams based on elastic analysis are constructed for evaluation of prestress forces ...

Finite element simulation of stretch flanging process was carried out in order to investigate the effect of process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite element simulation was done using FEM software package ABA...

Abstract Box girders with steel cantilevers underneath the deck are frequently used in design of composite bridges. Hereby, welded joints between main girder and transverse system have to endure fatigue loads. Current specifications for this joint, e.g., a tapering thickness top flanges at same position transition radius, complex manufacture provide higher resistance than necessary. This articl...

habilitation of patients who have undergone extensive surgery for eradication of neoplasm of the maxillae requires restoration of the functions of speech, mastication, and deglutition. The options for rehabilitation of these patients are surgical reconstruction or prosthetic restoration. According to Sharry,’ even when surgical techniques are available, prosthetic reconstruction is chosen most ...

The scattering of a fluid-structure coupled wave at a flanged junction between two flexible waveguides is investigated. The flange is assumed to be rigid on one side and soft on the other; this enables a solution to be formulated using mode-matching. It is shown that both the choice of the edge conditions imposed on the plates at the junction and the choice of incident forcing significantly aff...

The dynamic response of individual components in an assembled structure shows high accuracy compared to experimental measurements the system response. However, when it comes assemblies, conventional linear approaches fail deliver good accuracy, due uncertain and nonlinear mechanisms contact interface joints. Therefore, inherent dynamics interfaces needs be considered modeling structures. In thi...

Under severe earthquakes, eccentrically braced frames might experience large inelastic deformations, and the inelastic action is restricted primarily to the ductile links. In order to study the reasonable design method for links, seventy analyses of links are conducted to investigate the effect of different flange width-thickness ratio and length, fifty links are also designed to study the infl...

Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web gird...
