1. 6. Rapid prototyping with fiber composites - Manufacturing of an amphibious UAV

   University essay from KTH/Lättkonstruktioner

   Author : Zlatan Ramic; [2021]
   Keywords : CFD; FRP; CFRP; UAV; AUAV; FEM; Solid mechanics; fibre composites; ANSYS; lightweight structures; CFD; FRP; CFRP; UAV; AUAV; FEM; hållfasthetslära; fiberkomposit; ANSYS; lättkonstruktion;

   Abstract : Rapid prototyping has in the last few years gained an ever increasing central role in projects thanks to its agile benefits. Because of that, boundaries regarding what can be accomplished can be pushed and new techniques for achieving goals can be explored at a reasonable cost. READ MORE

3. 7. Crack growth based FEM with embedded discontinuities

   University essay from KTH/Hållfasthetslära

   Author : David Lindblom; [2021]
   Keywords : PUFEM; Fracture Mechanics; J2-plasticity; FEAP; Strong discontinuity; Variational formulation; XFEM; PUFEM; Brottmekanik; J2-plasticitet; FEAP; Diskontinuitet; variationskalkyl;

   Abstract : In recent years there have been a major developments in the computational mechanics community when it comes to modelling of fracture mechanics. There are now several well established numerical methods that are implemented in commercial programs such as: Phase Field Modelling, Enhanced Assumed Strain (EAS), Smeared Crack Methods, Extended Finite Element Method (XFEM) and Partition of Unity Finite Element Method (PUFEM).

4. 8. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Nitin Narayanaswamy; [2020]
   Keywords : Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

   Abstract : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. READ MORE

5. 9. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

   University essay from KTH/Lättkonstruktioner

   Author : Mara Santaniello; [2020]
   Keywords : ;

   Abstract : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. READ MORE

6. 10. Biomechanical Analysis of Implant plates for Mandibular Condyle fractures

   University essay from

   Author : Viswambik Rohit Kumar Dhurvasula; [2019]
   Keywords : Finite Element Analysis; Hydroxyapatite; Poly-L-lactic acid; stress shielding; Maxillofacial surgery.;

   Abstract : In the field of maxillofacial surgery, the treatment for the recovery of the fracture at condyle region of the mandible has been carried out using Bio-metals such as Titanium, Cobalt, Stainless-Steel because they were considered the standard materials for Implant plate devices for fracture fixation. Using these materials have led to undesired disturbances where the patient must undergo secondary surgery after recovery leading to exposure of the fracture site to the surrounding, metal-ion release into the human system, stress-shielding and interruption during imaging i.
