Influence of the moisture content on the shear strength of welded wood-to-wood connections

Yves Weinand, Bernhard Stamm, Benjamin Hahn, Georg Lorenz Rossmair

Friction welding of wood is an innovative process, able to join pieces of wood without additional adhesives. Because of its hygroscopic properties, the wood matrix absorbs humidity at the surface from the surrounding atmosphere. Its moisture content is str ...

Investigation of technological size effects of welding on the residual stresses and fatigue life of tubular joints made of structural steels S355 and S690

Alain Nussbaumer, Claire Acevedo, Farshid Zamiri Akhlaghi, Janna Krummenacker

The fabrication procedure changes when changing the size of the structural components. For the weldments, the change of the welding procedure leads to the change in residual stresses which consequently affects the fatigue life of the structure. The weld si ...

Simulation of the welding process of steel tube joints made of S355 and S690

Janna Krummenacker

Welding is an important joining method for the work with metals. During the welding process, the material is heated and deforms plastically which leads a change in microstructure in the heat affected zone, to complex residual stress distributions, and dist ...

Coupling quantum and continuum scales to predict crack tip dislocation nucleation

William Curtin, Derek Warner

A quantum-continuum multiscale coupling of Kohn-Sham density functional theory to continuum material is presented that can handle mechanics problems in metals when long-range stress fields are present, such as occurs for dislocations and cracks. The method ...
