  1. 1. Mechanical Parameter Characterization of Thin Polymer Films Using Digital Image Correlation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Anoop Vullaganti; [2021]
    Keywords : Digital Image correlation DIC ; Effect of spray paints; Pattern quality; Thin polymer film; Wrinking effect.;

    Abstract : Mechanical parameter characterization of very thin polymer films using digital im- age correlation is performed in this work. At present days DIC is widely used in the construction, food industries, and aviation. READ MORE

  3. 2. The Study of Buckling Behavior of Al-foil With Central Crack

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : YiPing Jin; FengYuan Wang; [2019]
    Keywords : Buckling; Critical Buckling Stress; Deflection; Membrane; Finite Element Analysis FEA ; Imperfection; Wrinkling;

    Abstract : The present paper studied the buckling phenomena of membranes under tensile load with and without central crack.  The studies of fracture mechanics are tested within certain conditions of membranes. The tensile test has been performed with Al-foil in different crack lengths, i.e. READ MORE

  4. 3. Wrinkling in packaging material: Experiments and thermo-mechanical stochastic modeling

    University essay from Lunds universitet/Hållfasthetslära

    Author : Linus Dahlström; David Johansson; [2018]
    Keywords : Stochastic; modeling; XCT; thermo-mechanical; Technology and Engineering;

    Abstract : As one of the world leaders in food packaging, it is in the interest of Tetra Pak⃝R to increase the understanding of packaging material and how it can better be virtually modeled, using finite element (FE) simulations. The aim of this thesis is to evaluate whether a stochastic approach can be taken to generate a more realistic response than a purely deterministic one, in the aforementioned models. READ MORE

  5. 4. Study of an axially loaded sandwich panel : Study based on finite element analysis and experimentation of a 1 mm flat profiled steel plate

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Navid Fathi; [2017]
    Keywords : Flat profile; Wrinkling; Crippling; FEM;

    Abstract : Sandwich panels produced by Isolamin AB are comprised of a core, such as polyurethane or mineral wool that is attached between two steel plates. The problem that the thesis attempts to solve is whether a flat profiled sandwich panel of 1mm can withstand loads from 3-storey modular house. READ MORE

  6. 5. Porcine pain face – identifying visible characteristics of pain in pigs

    University essay from SLU/Dept. of Clinical Sciences

    Author : Lina Göransson; [2016]
    Keywords : pain; porcine; pig; pain assessment; pain face; facial expressions; Capsaicin;

    Abstract : The sensation of pain is an important evolutionary adaptation, vital for the survival of an organism. Not only does it enable identification and subsequent avoidance of potentially harmful threats, it also allows for special tending of the affected and possibly injured area. READ MORE
