1. Bedömning av prediktiv förmåga för Finita Elementberäkningar med optisk töjningsmätning (DIC)
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : The goal of this thesis is to improve the predictive capability of Finite element (FE) by gathering data from experimental test and implement the characteristics into the material model that is used. FE is a commonly used method to predict the mechanical behavior of materials and components during applied forces. LÄS MER
2. Size effect in wood : Characterization of mechanical properties using digital image correlation method
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanikSammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER
3. Experimental Testing of EPS-foam
Master-uppsats, KTH/HållfasthetsläraSammanfattning : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

4. Investigation of the basic mechanics of edge cracking in sheet aluminum forming
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : As technology is developing in all automotive companies, car body designers have also investigated new materials such as composite and aluminum alloys. Designing modern car structures has also created various challenges in the production process, including formability limitations. LÄS MER
5. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. LÄS MER
