An experiment was developed to simulate the interface between liquid high manganese carbon steel and solid ultra-low alloyed steel in a thermal gradient, corresponding to the nugget/sheet interface of resistance spot welds. Despite the large difference in ...
Additive Manufacturing (AM) in whole and especially Selective Laser Melting (SLM) are already making a revolution in the way parts are designed and manufactured with the ability to produce lightweight parts with unprecedented complex geometries which are o ...
As fatigue cracks were discovered under the bridge deck of the 48 years old railway bridge Linthkanal-Brücke, located near the Ziegelbrücke town in Switzerland, a few studies were conducted to understand the mechanism behind the cracks formation. However, ...
Friction welding of wood is a bonding technology that can be used for joining timber elements, and in which the adhesive is formed from thermally modified cell wall material within the substrate during the welding process. In this paper, this principle is ...
When for steel liners of pressure tunnels and shafts high-strength steels are used, welded joints are subject to the risk of hydrogen induced cold-cracking in the base material. Longitudinal butt welded joints are critical regions as they are loaded transv ...
This paper investigates the fatigue upgrading of typical cover plate joint connections in existing steel bridge girders through cover plate extension. The upgraded detail is created by removing the existing transverse end weld, then welding the extension t ...
The recent development of high-strength (HSS) weldable steels has enlarged the range of design alternatives for the optimization of high-head steel-lined pressure tunnels and shafts (SLPT&S) in the hydropower industry. With the liberalization of the Europe ...
The method of manufacturing objects made of a first primary material such as ceramic, metallic or polymer materials on at least one workstation by selective laser melting (SLM) comprises the addition of at least a secondary material different from the prim ...
Remote laser welding which has benefits for both productivity and energy saving is receiving increased attention for automotive assembly lines. Introducing this innovative equipment requires a redesign process for assembly elements, for example to substitu ...
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 ...
