1. 11. Polyimide thin-ply composite

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : KHALID MOUANE; [2018]
   Keywords : Polyimide; thin-ply; microcracking; curing stress; mechanical loading;

   Abstract : Mechanical performance of composite structures is influenced by the accumulation of damage from the manufacturing process and throughout the whole service life. For instance, an aircraft is subjected to a combination of mechanical loading and the thermo-oxidative environment from the take-off to the landing. READ MORE

3. 12. Analysis of Ferrocement and Textile Reinforced Concrete for Shell Structures

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Mile Bezbradica; [2015]
   Keywords : textile reinforced concrete; shell structures; ferrocement; FEM; Technology and Engineering;

   Abstract : The purpose of this master’s thesis is to investigate the stiffness properties of three reinforcement materials for concrete shell structures: ferrocement, glass-fibre textile and carbon-fibre textile. Three types of strategies were used to analyse the properties of the materials, an analytical model, experimental beam prototypes and a numerical analysis. READ MORE

4. 13. Shear-Wave Splitting Observed in Local Earthquake Data on the Reykjanes Peninsula, SW Iceland

   University essay from Geofysik

   Author : Darina Buhcheva; [2014]
   Keywords : shear-wave splitting; local earthquakes; Iceland;

   Abstract : Shear-wave splitting is a phenomenon observed in almost all in situ rocks. Due to propagation through stress-aligned and fluid-saturated microcracks and fractures the initial shear wave splits into two almost orthogonal waves which propagate with different velocities along similar ray paths.
