Ultra low cycle fatigue of welded steel joints under multiaxial loading

Albano António De Abreu E Presa De Castro E Sousa

Extreme loading scenarios such as earthquakes, exceptional wind gusts or tides are characterized by very high amplitude and multidirectional cyclic loads applied to a structure. Ultra Low Cycle Fatigue (ULCF) arises in such cases and can be summarily defin ...

The austenite/lath martensite interface in steels: Structure, athermal motion, and in-situ transformation strain revealed by simulation and theory

William Curtin, Francesco Maresca

The austenite/martensite (fcc/bcc) interface is prevalent across many new classes of high-strength steels, and yet both its fundamental structure and its mechanism of motion remain uncertain in spite of decades of research. Here, atomistic simulations are ...

Fatigue behaviour of CHS tubular bracings in steel bridges

Alain Nussbaumer, José Joaquim Costa Branco de Oliveira Pedro, Cláudio Alexandre Pereira Baptista, Saad Kannuna

The structural solution for cross girder bracings or box girder diaphragms in steel bridges is often made with tubular elements, specially efficient if compression is required for structural behaviour. The connection between the tubular elements and the gi ...

Feasibility of iron-based shape memory alloy strips for prestressed strengthening of steel plates

Moslem Shahverdi, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

Iron-based shape memory alloys (Fe-SMAs) are advanced materials that can be used as prestressing elements for strengthening and rehabilitation of civil structures. In this paper, the results of a feasibility study on the application of shape memory effect ...

Proposed modeling approach of welding procedures for heavy steel plates

Dimitrios Lignos

A numerical modeling approach is proposed to assess the effectiveness of automatic submerged arc welding procedures for steel plates with thickness larger than 50 mm. The scope of study includes partial joint penetration butt welds, their numerical analysi ...

Lateral Torsional Buckling of steel bridge girders

Jean-Paul Lebet, Raphaël Thiébaud

The Lateral Torsional Buckling (L.T.B.) design of beams in buildings has received considerable attention over the last decades, and relatively similar improved design rules are now implemented in major design standards. On the contrary, it may be shown tha ...

Calibration of partial safety factors for fatigue design of steel bridges

Alain Nussbaumer, Luca D'Angelo

The aim of this paper is to propose a new framework for assessment of fatigue partial safety factors with focus on steel bridges welded joints. Fatigue resistance S-N curves for constant amplitude (CA) and variable amplitude (VA) loadings are defined using ...

Continuous atomic displacements and lattice distortion during fcc–bcc martensitic transformation

Cyril Cayron

The continuous matrices of atomic displacements and lattice distortion from face-centered-cubic (fcc) to body-centered-cubic (bcc) phases compatible with the hard-sphere geometry of iron atoms are calculated for different possible final orientation relatio ...

Experimental and numerical characterisation of heat flow during flame cutting of thick steel plates

Jean-Marie Drezet, Jean-Paul Lebet, Raphaël Thiébaud

Temperatures measurements during flame cutting of a thick steel plate and measurements of the extension of the fusion and heat affected zones and Vickers hardness after cutting have been performed. Additionally, a 3-D thermal model for simulation of flame- ...
