1. 16. Strain/Stress profile investigation of crystals mounted in an optical instrument via FEM simulation

   University essay from Lunds universitet/Industriell Produktion

   Author : Matheus Amarante Machado; [2023]
   Keywords : Modeling; Abaqus; Y2SiO5; Finite Element Modeling; Strain; Stress; Yttrium Orthosilicate.; Technology and Engineering;

   Abstract : Abstract This work is one of a series of related papers that were made in Lund University. They were done to analyze in a multi scalar way the Yttrium Orthosilicate crystals (YSO), analyzing the variation of material properties stemmed from the mounting, composition and other parameters in the optical properties of Yttrium Orthosilicate crystals.

3. 17. Strain Rate Characterization of Packaging Materials

   University essay from Lunds universitet/Industriell Produktion

   Author : Zichun Wang; [2022]
   Keywords : Paperboard; Strain rate; yield stress; Technology and Engineering;

   Abstract : This master thesis firstly introduced the basic knowledge of packaging materials through a literature survey focused on exploring the effect of strain-rate on mechanical properties of paperboard materials. By means of tensile tests and microscopic observation, the changes of mechanical properties such as yield strength, strain and Young's modulus of the two different paperboards used in laminated packaging materials for the two different package types Tetra Fino® Aspetic (TFA) and Tetra Brik® Aseptic (TBA) from Tetra Pak® were analyzed at strain rate ranging from 0.

4. 18. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

   University essay from KTH/Fiber- och polymerteknologi

   Author : Malin Eriksson; [2022]
   Keywords : dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

   Abstract : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. READ MORE

5. 19. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : David Aronsson Edström; Oskar Lundberg; [2022]
   Keywords : 3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

   Abstract : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. READ MORE

6. 20. Back analysis of rock mass properties in the regional fault zone under Lake Mälaren

   University essay from KTH/Jord- och bergmekanik

   Author : Jiaqi Liu; [2022]
   Keywords : Rock mass property; back analysis; tunnel deformation; optimization algorithm; numerical analysis; Bergmassans egenskaper; bakåtanalys; tunnleldeformation; optimeringingsalgoritm; numeriska analyser.;

   Abstract : The properties of the surrounding rock mass in underground projects have significant impacts on the design and construction. However, it is quite challenging to evaluate rock mass properties due to the great uncertainties of the geological conditions. READ MORE
