1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER
2. Evaluation of a computational method for natural fiber-reinforced plastics
Master-uppsats, KTH/HållfasthetsläraSammanfattning : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. LÄS MER
3. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. LÄS MER
4. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. LÄS MER
5. Characterization of commercially pure titanium under supercritical conditions : By means of hybrid numerical-experimental approach
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Material characterization was addressed by solving the inverse engineering problem to mechanical properties by means of finite element analysis and computational optimization. High-temperature and high strain-rate data from split Hopkinson pressure bar tests on commercially pure titanium were used in the study. LÄS MER
