1. 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
2. Forced response numerical investigation of a transonic compressor rotor
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER
3. Characterization of Kelvin Cell Cored Sandwich Structures with Analysis and Experiments
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : In order to satisfy the mechanical requirements for space structures, achieving lightweight designs is of the greatest significance. The primary focus of this study is the utilization of Kelvin cell core in the design of sandwich structures for space applications. LÄS MER
4. Methodology for analysis of vibration isolating systems
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. LÄS MER
5. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam
Master-uppsats, KTH/BetongbyggnadSammanfattning : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. LÄS MER
