  1. 1. Method Development & Analysis of Seals using FEM

    University essay from KTH/Maskinkonstruktion

    Author : Lovisa Svanborg Östlin; [2023]
    Keywords : FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Abstract : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. READ MORE

  3. 2. FEM analysis of existing buildings during renovation

    University essay from KTH/Hållfasthetslära

    Author : Agnes Nyberg; [2023]
    Keywords : Sturegallerian; Räumlich Finite Element Method; Euro code; Masonry; Steel amplifier; Sturegallerian; Räumlich Finita Element Metod; Eurokoder; Murverk; Stål förstärkning;

    Abstract : In this masters thesis the aim was to investigate a part of Sturegallerian in Stockholm to be reconstructed. The reconstruction did implicate that openings were to be established in an already existing masonry wall. READ MORE

  4. 3. Investigation of case hardened steel subjected to torsion: An experimental and numerical elastic-plastic material study

    University essay from KTH/Hållfasthetslära

    Author : Jonathan Fridstrand; [2022]
    Keywords : Torsion; Shear stress-strain relation; Elastoplastic material; Case hardened steel; Custom material model; Vridning; Skjuvtöjning och -spänning; Elastiskt-plastiskt material; Sätthärdat stål; Anpassad materialmodell;

    Abstract : There is currently a knowledge gap regarding the plastic material properties of many steel types that Atlas Copco use in their high torque power tools. This makes it difficult to fully utilise the capabilities of the Finite Element Method (FEM) to aid the developmental process. READ MORE

  5. 4. 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

  6. 5. 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
