  1. 6. Thin metal patch to FRP propeller: Experimental testing of bonding systems

    University essay from KTH/Lättkonstruktioner

    Author : Mårten Kreiss Amberg; [2015]
    Keywords : ;

    Abstract : To enable the use of carbon fibre reinforced polymer (CFRP) propellers for merchant vessels, the problem of cavitation must be solved. The matrix of the FRP is generally brittle and more sensitive to cavitation erosion than the more conventional metal propeller blades. Nakashima Propeller Co. READ MORE

  3. 7. Robust repair methods of primary structures in composite

    University essay from Hållfasthetslära

    Author : Marcus Ramström; Mattias Gungner; [2013]
    Keywords : Composite; Repair; Scarf joint; Step joint; Fabric; Tape; FEM;

    Abstract : A request of material change when performing repairs on composite parts of SAABs JAS 39 Gripen has lead to the initiation of this project. The aim is to create a quicker and more robust repair method. READ MORE

  4. 8. Autonomic Dynamic Load Balancing of Parallel SAMR Applications

    University essay from Avdelningen för teknisk databehandling

    Author : Karl Ljungkvist; [2011]
    Keywords : SAMR; parallel; adaptive; refinement; structured mesh; partitioning; Chombo; Meta-partitioner;

    Abstract : When solving partial differential equations using finite difference methods on structured meshes, adaptive refinement can be used to increase the accuracy of the solution in an efficient manner. When implementing solvers using structured adaptive mesh refinement for modern parallel computer systems, an important task is the partitioning of the grid hierarchy over the available processors.

  5. 9. Vibro-acoustic analysis of a satellite reflector antenna using FEM

    University essay from Institutionen för fysik

    Author : Johannes Sikström; [2011]
    Keywords : finite element method; FEM; acoustics; vibrations; vibro-acoustic; analysis; NASTRAN; PATRAN; satellite; fluid-structure; fsi; structure-acoustic; random analysis;

    Abstract : The acoustic environment generated during launch is the most demanding structural load case for large, lightweight satellite reflector antennas. The reflector is exposed to extremely high sound pressure levels originating from the structural excitation of the rocket engines and exterior air flow turbulence. READ MORE

  6. 10. A Patch-based Partitioner for Structured Adaptive Mesh Refinement : Implementation and Evaluation

    University essay from Institutionen för informationsteknologi

    Author : Abbas Vakili; [2008]
    Keywords : ;

    Abstract : To increase the speed of computer simulations we solve partial differential equations (PDEs) using structured adaptive mesh refinement (SAMR). During the execution of an SAMR-application, finer grids are superimposed dynamically on coarser grids where a more accurate solution is needed in the computation area. READ MORE
