1. 16. Numerical analysis of a bearing strength in delaminated composite joint

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Olavi Kukkonen; [2023]
   Nyckelord :Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

   Sammanfattning : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

3. 17. Evaluation of IMO second-generation intact stability criteria and examination of different fishing vessel designs to dead ship condition and excessive acceleration failure mode

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Pavlos Liatsis; [2023]
   Nyckelord :Ship Design; Second Generation Intact Stability Criteria; Excessive Acceleration; Fishing Vessels; Skeppsdesign; andra generationens intakt stabilitetskriterier; kraftiga acceleration; fiskefartygsskrovs;

   Sammanfattning : The main objective of this project is to investigate the applicability of the IMO second-generation intact stability criteria in enhancing the process of designing fishing vessels, which often face stability challenges due to their narrow hulls and harsh operating environments. The study involves analyzing the impact of these criteria, specifically focusing on dead ship conditions and Level 1 and Level 2 excessive acceleration criteria, on the design of three fishing vessels.

5. 19. Evaluating electrolyser setups for hydrogen production from offshore wind power : A case study in the Baltic Sea

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Kenzo Franzén; [2023]
   Nyckelord :electrolysis; energy systems modelling; green hydrogen; offshore wind power; power-to-x; electrólisis; energía eólica marina; hidrógeno verde; modelado de sistemas de energía; power-to-x;

   Sammanfattning : As part of the transition towards a fully sustainable energy system, green hydrogen shows great potential to decarbonise several hard-to-abate sectors. To provide the fossil-free electricity required for electrolysis, offshore wind power has emerged as a suggested option. LÄS MER

7. 20. Incorporating Flax Fiber Composites in Hypercar Panels

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Hanna Öster; Sara Isorena Guðjónsdóttir; [2023]
   Nyckelord :sound transmission loss; coincidence frequency; sound pressure level; flax fibre; carbon fibre; ljudtransmission; koincidensfrekvens; ljudtrycksnivå; linfiber; kolfiber;

   Sammanfattning : This thesis investigates sound transmission loss through flat finite panels using composite materials, which incorporate both carbon and flax fibres. The study wascarried out by performing FEM simulations developed and validated in steps. Thevalidation process was time-consuming but crucial in ensuring the model’s reliability. LÄS MER
