One doctoral position is offered to work in the framework of the PRECISE project (Numerical methods for PREdicting the behaviour of CIvil StructurEs under water natural hazards – MINECO - BIA2017-83805-R)
The ultimate goal of PRECISE is to aid engineers, planners and other relevant stakeholders to take decisions regarding the design and implementation of mitigation measures to protect population, civil infrastructures and the environment under outstanding water flow events induced by natural hazards (floods, spills, tsunamis etc). This will be achieved through the development and experimental validation of a new generation of mathematical models and computational methods for the study of natural hazards involving flows with particles of different sizes (hereafter called particulate flows) and their interaction and damaging effects on structures and landscape. These computational methods will allow to solve Particulate-Fluid-Structure-Interaction (PFSI) problems to obtain an accurate and reliable prediction of the behaviour of landscape and constructions under extreme water hazards. The constructions of interest are dams, dykes, breakwaters, buildings, bridges and similar structures. The natural hazards considered include flash floods generated by heavy rain, or water overspills due to the collapse of dams, dykes and reservoirs under landslides and earthquakes, as well as slurry flows and tsunami flows, among others. Despite the research deployed in this field in the last few decades, the study of the deformation and failure of a construction and the erosion of a landscape area under a particulate water stream is still far from being a real possibility using the currently available computational resources.
In PRECISE we will develop and integrate continuous, particle and discrete numerical techniques based on the research conducted during the last years by the principal investigators on an innovative combination of particle-based methods (such as the Particle Finite Element Method, PFEM and the Material Point Method, MPM) and the Finite Element Method (FEM) and, in particular, on the blending of these techniques with the Discrete Element Method (DEM). The practical objectives of the research are:
