Abstract: The high temperatures induced during the welding process cause transient thermal stresses and non-continuous plastic strains around the weld. Uneven heating and cooling processes together with these plastic strains result in residual (welding) stresses, [1]. This paper deals with the development of plastic zones, related to welding stresses and their effects on the bearing capacity from a Civil-engineering perspective.

Abstract: In this paper, one certain space under bridge which was used as a storehouse has been simulated numerically. The flow was considered turbulent and buoyant. A simple geometry was adopted, consisting of a room with a door that plays the role of inlet and another of outlet for the air. Four bundles of wood burners which considered as a volumetric heat source were placed evenly in the space. The problem was simulated by using the RNG K-ε turbulence model, modified to account for buoyancy effects. Several useful results were obtained.
