  1. 1. Characterization of commercially pure titanium under supercritical conditions : By means of hybrid numerical-experimental approach

    University essay from KTH/Materialvetenskap

    Author : Ricardo Rodríguez; [2022]
    Keywords : ;

    Abstract : Material characterization was addressed by solving the inverse engineering problem to mechanical properties by means of finite element analysis and computational optimization. High-temperature and high strain-rate data from split Hopkinson pressure bar tests on commercially pure titanium were used in the study. READ MORE

  3. 2. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Axel Hallén; Jacob Hjorth; [2022]
    Keywords : Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

    Abstract : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. READ MORE

  4. 3. Material characterization of 316L

    University essay from Lunds universitet/Hållfasthetslära

    Author : Rita Iteka; Pardis Adibi; [2019]
    Keywords : FEM; steel; 316L; tensile test; material behaviour; material models; Technology and Engineering;

    Abstract : At Tetra Pak, general knowledge of food and beverage processing is of great importance. This in turn, depends on the equipment used for the particular process. One of these equipment consists of deformed tubes made of stainless steel 316L. The aim of the present work is to get an understanding of the material 316L. READ MORE

  5. 4. Burst test analysis of metal sandwich wall panels

    University essay from KTH/Lättkonstruktioner

    Author : Viktor Krödel Jonsson; [2015]
    Keywords : ;

    Abstract : In this report, an investigation of some of the most common damage models available in literature is performed. Their ability to predict ductile failure of metals will be compared and a specific focus is put on burst failure prediction of the cooling channels inside a sandwich wall structure. READ MORE

  6. 5. Experimental investigation of the strain rate dependence of SS2506 gear steel

    University essay from KTH/Materialvetenskap

    Author : Karin Ekström; [2013]
    Keywords : ;

    Abstract : hot peening is a surface treatment used to increase the fatigue strength of metallic components, for example gears, and it is of great interest to be able to model and simulate the effect of this treatment in order to save time and money. An important parameter that has to be considered when modeling the peening situation is the strain rate dependence of the target material. READ MORE
