Doctoral Thesis

OverviewThe transportation sector is one the largest contributors to European Union (EU) greenhouse gas (GHG) emissions and as such, is strongly impacted by the EU regulations that aim to reduce these by at least 55% by 2030, compared to 1990 levels. This has drastically changed the transportation landscape, especially affecting the car and van fleets, switching from fossil fuel powered Internal Combustion Engine (ICE) vehicles to those that are either plug-in hybrids (PHEV) or battery electric (BEV). Unfortunately, the electrification of the transportation is not enough to accomplish the ambitious goal of being a climate-neutral continent by 2050, as more actors exist in the automotive value chain. Material suppliers that offer for example, cast, rolled or extruded solutions and Original Equipment Manufacturers (OEM) that utilising forming processes create end products, heavily influence the GHG emissions of such value chain. From the point view of the mechanical and structural design, the electrical mobility has brought two of the most severe changes with respect to the ICE vehicles are (i) the overall weight increase of the vehicles due to the weight of the battery pack and (ii) the drastic motor configuration change from the front or rear to the bottom of the cars. These changes imply that the OEMs together with the car manufacturers have to certify new products and components that might have a severe repercussion on the safety performance of the vehicle. The weight increase together with the battery life restrictions has pushed the industry towards a lightweight mindset increasing the aluminium alloy usage in 25-27% with respect to a typical ICE.Si sus habilidades, experiencia y cualificaciones coinciden con las de esta descripción del puesto, no demore su solicitud.ObjectivesThe main objective of the project in which this PhD will be encompassed, is to develop intelligent and technologically innovative solutions that aim to achieve metal forming industry’s ambition of carbon footprint and cost reduction, oriented towards the most demanding applications where extreme loading conditions, i.e. high loading rates and elevated temperatures, apply. To achieve this, it will investigate the use of scrap tolerant or low carbon aluminium alloy products, either stamped or extruded, for EV specific and armour components in crashworthiness and impact scenarios aiming to reduce the GHG emissions. To achieve this target, and to tackle the afore-mentioned challenges we will :Assess the feasibility of use and impact of low carbon and / or scrap-tolerant alloysDevelop experimentally-validated high-fidelity advanced computational constitutive modelsDevelop the technology to design more efficient hot forming processesMechanics-informed data-driven machine learning models for faster and more efficient analysis of forming processes and safety assessmentInvestigate the performance of aluminium protective structures designed for EVsFundingThis four-year predoctoral position is fully funded by the “Agencia Estatal de Investigación” (AEI) through the iSAFE (PID2 OB-I00) “Generación de Conocimiento 2024” project.
