  1. 36. Numerical simulations of energy absorbing boundaries for elastic wave propagation in thick concrete structures subjected to impact loading

    University essay from Institutionen för fysik

    Author : Daniel Olsson; [2012]
    Keywords : Numerical simulations; elastic media; wave propagation; concrete; impact loading; energy absorbing boundaries; longitudinal; primary wave; secondary wave; shear; Rayleigh damping; Rayleigh wave;

    Abstract : As many of the world’s nuclear power plants are near the end of their supposed life span a need arise to assess the components crucial to the safety of these plants. One of these crucial components is the concrete reactor confinement; to assess its condition, non-destructive testing (NDT) is an attractive method. READ MORE

  3. 37. What microcavities can do in photonics : coupling resonances and optical gain

    University essay from KTH/Beräkningsbiologi, CB; KTH/Mikroelektronik och tillämpad fysik, MAP

    Author : Nicolas Innocenti; [2009]
    Keywords : optical microcavities; laser; finite elements method;

    Abstract : The present master's thesis deals with numerical modeling of solid-state micrometrical-sized polymeric dye lasers, commonly denoted as microcavities. It is part of a large research initiative carried out in the optics group, at the MAP (Microelectronics and Applied Physics) department in KTH (Kungliga Tekniska Högskolan - Royal Technical School) and targeted towards the design and manufacturing of micro- and nano-scaled polymeric components for nano-photonics, primarily lasers.

  4. 38. Component Meshing Methodology

    University essay from Institutionen för ekonomisk och industriell utveckling

    Author : Henrik Öhrblad; Henrik Berglund; [2008]
    Keywords : distortion; mesh quality; FEM; tetrahedra; solid elements; SimLab; sensitivity study;

    Abstract : In order to achieve results that are reliable when using the finite element method one has to use an acceptable element mesh with respect to the shape and size of the elements. As a help to produce an acceptable mesh there are quality criteria that must be fulfilled in most pre-processors. READ MORE

  5. 39. A finite element based design tool for point fixed laminated glass

    University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Byggnadsmekanik

    Author : Jens Malmborg; [2006]
    Keywords : stress extrapolation; 15-node wedge element; wedge element; Fortran; Python; toughened glass; laminated glass; bolt fixed glass; FEM; finite element analysis; discontinuous stress distribution; sparse matrix; Technology and Engineering;

    Abstract : In this master’s project, a design tool for bolt fixed laminated glass was developed, based on linear-elastic finite element theory. The program produces images of the deflections and stress distributions in bolted glass panes. READ MORE

  6. 40. Metamodel-based Optimization of an Electromagnetic Stirrer

    University essay from KTH/Optimeringslära och systemteori

    Author : Karolina Olofsson; []
    Keywords : ;

    Abstract : An electromagnetic stirrer (EMS) is a device widely used in metal melting processes. An EMS is normally placed under the bottom of a metal melting furnace. The presence of an EMS establishes a movement of the melts inside the furnace through the interaction between the electromagnetic force generated by the stirrer and the metallic melts. READ MORE
