  1. 11. In-plane bi-axial testing of thin paper

    University essay from KTH/Hållfasthetslära

    Author : Asad Ali; Danay Michael; [2022]
    Keywords : ;

    Abstract : During its lifetime, a beverage package is subjected to a complex loading history where the loading, in general, is multiaxial. Hence, to optimize the performance of the package, knowledge of the material’s anisotropic multi-axial deformation and subsequent failure is necessary. READ MORE

  3. 12. Strain rate-dependent mechanical properties of high-density polyethylene(HDPE)

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Oscar Andersson; Alexander Wiklund; [2022]
    Keywords : HDPE; strain rate; DIC; inverse calibration; Abaqus; HDPE; töjningshastighet; DIC; Inverskalibrering; Abaqus;

    Abstract : In today’s packaging industry HDPE is widely used and correct understanding of itsproperties and how to model them is of vital importance. HDPE is a semi-crystallinepolymer with a known strain rate dependence, that is a higher yield and lower strainto failure at higher strain rates. READ MORE

  4. 13. Non-Linear strain paths in Sheet Metal Forming

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Anton Eriksson; [2021]
    Keywords : Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Abstract : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. READ MORE

  5. 14. Tensile strength reduction for insufficient thread engagement A FEM study of a wall-shoe assembly

    University essay from KTH/Hållfasthetslära

    Author : Henrik Larsson Sevon; [2021]
    Keywords : Solid Mechanics; Tensile strength; Wall-shoe; Thread engagement; Hållfasthetslära; Draghållfasthet; Väggsko; Gängingrepp;

    Abstract : The purpose of this master thesis is to determine whether or not it exist, a model that can describethe reduction in strength, due to missing threads in a bond between a bolt and nut. And how thereduction in strength might effect a wall-shoe assembly, used to connect a wall to another wall or aconcrete base plate. READ MORE

  6. 15. FE-Modelling of a Joint for Cross-Laminated Timber

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

    Author : Linus Ekhagen; [2021]
    Keywords : cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

    Abstract : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. READ MORE
