The mechanical and optical features of glass have propelled its use as a structural material resulting in a multiplication of its applications especially within the construction and automotive sectors. The tensile strength of glass, however, is limited because of the existence of surface flaws. For this reason, glass is most often heat treated befo...

El vidrio es ampliamente utilizado en aplicaciones estructurales, estando presente en sectores como el sector de la automoción o el sector de la construcción. El comportamiento estructural del vidrio depende principalmente de la calidad superficial, dado que la apertura o propagación de grietas superficiales reduce drásticamente su resistencia. Por...

The objective of this work is to establish pertinent criteria allowing an optimal alternative to be chosen for calculating the inputs needed to make Run/Repair/Replace decisions and to program inspection plans for cracked wind turbine bearing rings. With this aim, the growth of a hole-edge through-crack was predicted analytically, simulated and mea...

The protection of the viral genome during extracellular transport is an absolute requirement for virus survival and replication. In addition to the almost universal proteinaceous capsids, certain viruses add a membrane layer that encloses their double-stranded (ds) DNA genome within the protein shell. Using the membrane-containing enterobacterial v...

Residual stress (RS) pattern of thick T-joint welds, which directly affects fatigue life, varies considerably depending on the thickness and number of passes. Nowadays, most approaches to predict fatigue life do not consider RS real value due to the difficulty of estimating them, hence, they tend to be conservatives. However, recent works have demo...

Gas metal arc welding (GMAW) is one of the most used joining method in the industry. However, one of the main problems of this process is the generation of residual stresses which have direct impact on the fatigue life of welded components. Nevertheless, residual stress pattern prediction is complex and requires the simulation of the welding proces...

Aluminium alloys are more and more important for the automotive industry due to their high strength to weight ratio and their elevated ductility; they are used for many different parts in automobiles as exterior panels, structural parts, brake housings and others. However, their formability at room temperature is limited. This inconvenient can be i...

Purpose: Magnesium alloys are especially appropriate to decrease vehicle weight and consequently reduce fuel consumption. However, forming limitations regarded to their low formability at room temperature are found when being manufactured by conventional forming processes. Consequently, development of new forming techniques, such as warm tube hydro...

Hydroforming is well known in steel applications for automotive industry, where complicated shapes can be get with high strength to weight ratios. Nevertheless, the poor formability of light alloys at room temperature has limited the application of hydroforming technology for aluminum and magnesium parts. Increasing the temperature of these materia...
