The development of iron British piers in the XIX century. The discovery of new materials

Materiales de Construccion, 2011
In this article, the authors study the decadence of wood piers along XIX century, mainly because of problems inherent to the attacks of invertebrates. Soon, the wood structures will be substituted by iron ones, appearing two extraordinary materials, cast

Influence of the Depth of Friction-welded Dowels on the Strength of Rotary Welded Joints

BioResources
One of the important factors in rotary welding is the depth of welding of the dowel as well as the direction of welding of the dowel. In the studied interval (welding depth of 15 to 30 mm), the pull-out force increased when welding the dowel parallel to ...
