  1. 21. Structural optimization of electronic packages using DOE

    University essay from KTH/Hållfasthetslära

    Author : Robin Johansson; [2020]
    Keywords : Design of experiments; DOE; Structural optimization; Electronic packages; DOE; Försöksplanering; Strukturoptimering;

    Abstract : The reliability of a mechanical system containing electronic packages is highly affectedby the environment the system is stationed in. The difference and fluctuationsbetween the ambient temperature and the operating temperature of the electronicpackage cause accumulation of inelastic strains in the package components thusdecreasing the service life.

  3. 22. Design of multilayer paperboard for optimisedcompression strength

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ali Salem Ali; [2020]
    Keywords : Compression strength; Paper; Cardboard; Dynamique Formette; Dynamic sheet former; SCT; Shortspan compression test; fibre; fibre properties; fiber; fiber properties; Multilayer;

    Abstract : This master thesis was issued by BillerudKorsnäs Gruvön. The focus of this thesis was theinvestigation of the effects different fibre types has on the compression strength of the whole paper product. This stems from wanting to better understand how to produce a better paperboard construction with respect to stacking, storage, and transport. READ MORE

  5. 24. Numerical analysis of paperboard delamination using cohesive elements

    University essay from KTH/Hållfasthetslära

    Author : Markus Johansson-Näslund; [2020]
    Keywords : ;

    Abstract : A new test method for measuring the shear strength associated with mode III delamination of paperboard is studied with the purpose of reducing the size of the test configuration. The method, which uses a split cantilever beam (SCB) specimen, measures the shear strength indirectly through the fracture resistance. READ MORE

  6. 25. Understanding the effect of material composition and microstructure on the hot corrosion behaviour of plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Ehsan Najafi; [2019]
    Keywords : Thermal barrier coatings; molten salt infiltration; TBC variations; hot corrosion test;

    Abstract : Thermal barrier coatings (TBC) are used in the hot sections of gas turbine engine in order to insulate the substrate at high temperature. Molten salt infiltration retards the durability of TBCs. The current standard material, i.e. READ MORE
