The storage of Weapons Grade Plutonium (WGPu) pits has prompted this study of the effects of alpha irradiation on stainless steel. Energetic alpha particles emitted from the decay of plutonium isotopes continually introduce helium into the metal cladding that surrounds the pits. The continuous introduction of helium into a metal leads to the degradation of its mechanical properties. The integri...

this study evaluates two different types of techniques for concrete hollow-block sections reinforced with traditional steel rebars and wire meshes, and compares their structural behaviour to that of an ordinary reinforced concrete beam section. the comparisons are based on the responses both before and after they were repaired with glass fibre reinforced polymers (gfrp). the specimens were subj...

In this paper, we present a comparison between the older DSTV file format and the newer version of the IFC standard, dedicating special attention of its impact in the robotization of welding and cutting processes in the steel structure fabrication industry. In the last decade, we have seen in this industry a significant increase in the request for automation. These new requirements are imposed ...
