Conceptual design of 1000 m scale steel-UHPFRC composite truss arch bridge

Jieping Zhu, Xiujiang Shen

Excessive self-weight and difficulty in construction are the main issues confronted by super-long-span arch bridges. To address these issues, a conceptual design of steel-ultra-high performance fibre-reinforced concrete (UHPFRC) composite truss arch bridge ...

Recommendations for Improved Welding Procedures for Thick Steel Plates Through Thermo-Mechanical Analysis

Dimitrios Lignos

Welding of steel plates is accompanied by residual stresses that increase as the constraint provided by the welded components becomes greater. Consequently, crack initiation has been reported after welding thick plates due to the high residual stresses dev ...

Aramid/glass fiber-reinforced thermal break - thermal and structural performance

Thomas Keller, Julia De Castro San Roman Fest, Kyriaki Goulouti

Energetically weak points in thermally insulated building envelopes are formed by thermal breaks that are implemented to structurally connect external balconies to internal slabs. Current thermal breaks comprise stainless steel bars that penetrate the insu ...

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 ...

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

Jean-Paul Lebet, Jean-Marie Drezet, 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- ...

Sputtered titanium oxynitride coatings for endosseous applications: Physical and chemical evaluation and first bioactivity assays

Rosendo Sanjines

Titanium oxynitride coatings (TiNxO3,) are considered a promising material for applications in dental implantology due to their high corrosion resistance, their biocompatibility and their superior hardness. Using the sputtering technique, TiNxO3, films wit ...

Recent progress in research on tungsten materials for nuclear fusion applications in Europe

Nadine Baluc, Ho Ling Li, Lyubomira Veleva, Antoine Cyril David Hoffmann

The current magnetic confinement nuclear fusion power reactor concepts going beyond ITER are based on assumptions about the availability of materials with extreme mechanical, heat, and neutron load capacity. In Europe, the development of such structural an ...

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

Jean-Paul Lebet, Raphaël Thiébaud

This paper concentrates on the characterization of the heat flow present during flame cutting of 60 mm thick steel (S355N) flanges, a typical size used in the fabrication of bridge girders. Experimental results are associated with a finite element analysis ...
