  1. 1. Temperature distribution and charring penetrations in timber assemblies exposed to parametric fire curves : Comparisons between tests and TASEF predictions

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Isac Andersson; Niklas Ek; [2017]
    Keywords : TASEF; Delamination; Timber beams; Parametric fire curves; Fire tests; Charring; Eurocode; TASEF; Delaminering; Träbalkar; Parametriska brandkurvor; Brandtester; Förkolning; Eurocode;

    Abstract : Four furnace tests have been performed using two different parametric fire curves and the results are compared with computer simulations and Eurocode calculations. What differentiates the parametric fire curve from other fire curves is in particular the cooling phase, something that has proven to be hard to model for timber structures. READ MORE

  3. 3. Master thesis within light warhead for support weapon : Investigation of defects, methods and requirement specifications in order to get a shell body shatter free

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Adam Jansson; [2016]
    Keywords : warhead; support weapon; shell body; shatter free; defect; method; carbon fibre; epoxy; crack; delamination; porosity; CFRP; CFRE; NDT; verkansdel; understödsvapen; granathylsa; splitterfri; defekt; metod; kolfiber; epoxi; spricka; delaminering; porositet; OFP;

    Abstract : At launching the shell body, especially the backplane of the shell body, will be exposed to very high stresses due to acceleration, pressure and increased temperature from the propellant combustion. Defects in the shell body could in worst case for example result in high temperature gas leakage into the warhead and thereby ignite the explosives before exiting the launcher. READ MORE

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

    University essay from Umeå universitet/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
