1. 26. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anders Tolf; Markus Johannesson; [2022]
   Keywords : Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

   Abstract : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. READ MORE

3. 27. 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

4. 28. UV Curable Polymers for use in Additively Manufactured Energetic Materials

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexis Delorme; [2022]
   Keywords : Additive manufacturing; 3D printing; UV curing; mechanical properties; solid rocket motor; propellant; polymers; depth of cure; Additiv tillverkning; 3D-utskrift; UV-härdning; mekaniska egenskaper; fast-bränsleraketmotor; drivmedel; polymerer; härdningsdjup;

   Abstract : Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. READ MORE

5. 29. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

   University essay from KTH/Hållfasthetslära

   Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
   Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

   Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

6. 30. The influence of post-buckling damage on the tensile properties of single wood pulp fibers

   University essay from KTH/Hållfasthetslära

   Author : Raphael Andreolli; [2021]
   Keywords : Solid Mechanics; single fiber testing; wood pulp fibers; post-buckling damage; experiments; development of testing methods; tensile properties; tensile stiffness; tensile strength; Hållfasthetslära; enskild fiber testning; pappersmassa fiber; skada efter knäckning; experiment; utveckling av testutrustning; dragegenskaper; dragstyvhet; draghållfasthet;

   Abstract : The rapid growth of plastic waste from food packaging around the world demands renewable substitutes, such as natural fibers and biocomposites. Wood fibers are natural fibers extracted from trees and are commonly used in packaging. READ MORE
