Residual stresses must be taken into account when evaluating the stability of a steel bridge girder. Residual stresses are unavoidable, as manufacturing processes for steel plates introduce thermal residual stresses in the material. For welded built-up sec ...
The weld-induced residual stresses in a tubular planar K-shaped connection made of construction steel grades S355J2H and S690QH are evaluated using three-dimensional finite element models in thermo-mechanical simulation of welding process. Both lumped sing ...
An article made of an alloy of the general formula Pt1-a-bMa(B1-xMdx)b in which i) M stands for one or a mixture of metallic element(s) of the group Zr, Ti, Fe, Ni, Co, Cu, Pd, Ag, Al ii) Md stands for one or a mixture of several metalloids of the group Si ...
Improving the energy efficiency of cooling systems can contribute to reduce the emission of greenhouse gases. Currently, most microelectronic applications are air-cooled. Switching to two-phase cooling systems would decrease power consumption and allow for ...
The biomedical industry has an increasing demand for dissimilar metal joining processes, which are used for complex configuration designs, such as guidewires and other intravascular interventional devices. Their production becomes more and more challenging ...
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 ...
Variability of the internal friction angle with temperature is studied in a boundary value problem numerically simulating the impact of a cylindrical heat source on the stress and strain in soil mass in which it is emplaced. Even if the thermal increase of ...

Welding processes are extensively used to assemble components in many manufacturing industries, such as aeronautics, construction, energy and automotive. To increase their productivity, constructors try to reduce manufacturing time. This involves for weldi ...
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 ...
The effect of the temperature dependence of the internal friction angle is studied in a boundary value problem simulating the impact of a cylindrical heat source on the soil mass in which it is embedded. This follows a previous study which shows that such ...
