Moreira Filho, Carlos Augusto (Date of defense: 2022-07-21)
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized by multiple ...
Nasika, Christina (Date of defense: 2022-06-28)
The latest monitoring and asset management technologies for large infrastructures involve digital representations that integrate information and physical models, exist in parallel to the real-life structures, and are ...
Riba Porras, Sergi (Date of defense: 2022-06-14)
Over the last 40 years, in Europe in general and in many mountainous regions in particular, there have been major instances of severe flood episodes (more than 100) which have resulted in more than 700 deaths and billions ...
Regalado López, Francisco Javier (Date of defense: 2022-06-22)
The constant and rapid population growth goes hand in hand with an increased demand for services that governments have the duty to satisfy with the problem of limited financial resources. Transport infrastructure is one ...
Valdés Alonzo, Gabriel Rolando (Date of defense: 2022-06-03)
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing models can lead ...
Cavaliere, Fabiola (Date of defense: 2022-04-06)
In order to be worldwide competitive, the automotive industry is constantly challenged to produce higher quality vehicles in the shortest time possible and with the minimum costs of production. Most of the problems with ...
Delgadillo Ayala, Rick Milton (Date of defense: 2022-03-23)
In recent years the scientific community has been developing new techniques in structural health monitoring (SHM) to identify the damages in civil structures specially in bridges. The bridge health monitoring (BHM) systems ...
Khadivipanah, Peiman (Date of defense: 2022-02-03)
The main objective of this thesis is to describe and implement a rate-dependent (viscoplastic) constitutive equations for copper based canister using a single internal state variable and use it for modelling disposal schemes ...
Hashemi, Mohammad Reza (Date of defense: 2022-02-22)
In numerous applications, two-phase liquid-gas transport at sub-millimeter length scales plays a substantial role in the determination of the behavior of the system at hand. As its main application, the present work focuses ...
Ritter, Josias Manuel Gisbert (Date of defense: 2021-07-16)
Flash floods are one of the most devastating natural hazards, claiming numerous lives and tremendous economic losses. One of the main reasons for their catastrophic potential is the limited time available for precautionary ...
Palacios Pierluissi, Andrea Viviana (Date of defense: 2021-09-16)
Seawater intrusion (SWI) consists in the movement of seawater (SW) into freshwater (FW) aquifers, contaminating drinking water resources. SWI, along with the parallel reduction of Submarine Groundwater Discharge may lead ...
Tosi, Riccardo (Date of defense: 2021-12-21)
Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ...
Germano, Nicola (Date of defense: 2021-12-14)
