1. 1. Green Raven Structural Design : Optimization of Internal Structure for Blended Wing Bodies

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Oscar Ehrler; Anton Holmén; [2022]
   Keywords : UAV; Blended wing body; BWB; wing structure; Scots pine; Fiber reinforced plastic; FRP; Off axis loading of fiber reinforced plastic; wing mount;

   Abstract : The student inclusive Green Raven project of the KTH-Aero faculty requireda small blended wing model of their new flying wing design. The small scalemodel will be used for various flight tests. The goal of this specific project was tocreate an internal structure for the small scale model, including an outer shell. READ MORE

3. 2. Validation of An Iteration Free Material Model for Paperboard (NEO)

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

   Author : Samuel Thomas Staines; [2022]
   Keywords : Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

   Abstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE

4. 3. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes

   University essay from KTH/Lättkonstruktioner

   Author : Ming Kai Chea; [2019]
   Keywords : ;

   Abstract : Steering of prepreg tows in an automated fibre placement (AFP) process allows geodesic layup trajectory over a doubly-curved surface, as well as the potential to improve the efficiency of composite structures by tailoring their stiffness. However, defects (such as out-of-plane buckling and tow pull off) are commonly generated when the steering radius exceeds a critical limit, which impact the mechanical properties of the finished product.

5. 4. Designing radiation protection for a linear accelerator : using Monte carlo-simulations

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jonatan Lindahl; [2019]
   Keywords : linac; linear accelerator; accelerator; mega voltage photons; spectra determination; high energy photons; Monte carlo; simulations; radiation transport; dose; radiation; radiation protection;

   Abstract : The department of Radiation Sciences at Umeå University has obtained an old linear accelerator, intended for educational purposes. The goal of this thesis was to find proper reinforced radiation protection in an intended bunker (a room with thick concrete walls), to ensure that the radiation outside the bunker falls within acceptable levels.

6. 5. Evaluation of the wavefronts and spatial structures of ultrashort pulses passing through a micro-channel plate

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Simon Ek; [2019]
   Keywords : high-order harmonic generation; HHG; micro-channel plate; MCP; attophysics; Physics and Astronomy;

   Abstract : The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. READ MORE
