  1. 6. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Sohail Anwar; [2020]
    Keywords : Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Abstract : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). READ MORE

  3. 7. 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

  4. 8. Thermo-Mechanical Fatigue Assessment of Marine Boiler : Using linear Finite Element Analyses

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Adefemi Samuel Alagbada; [2020]
    Keywords : Marine Boiler; FEA; Thermo-mechanical Loading; LEFM; Paris law; Flaws; RAO.;

    Abstract : This thesis is on fatigue crack growth assessments of a thermomechanical loaded Marine Boiler- Sunrod CPDB12. The installation position of the marine boiler in the ship in relation to its fatigue life under mode 1 loading is investigated. READ MORE

  5. 9. Stepping Down Fatigued or Not: What Makes Flight Crews Decide to Step Down From Duty.

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Vincent Steinmetz; [2020]
    Keywords : Fatigue; Variability; Aviation; FRMS; Fatigue Risk Management; Flightcrew; Decision making; NDM; RPD; Complexity; FLMU06; Social Sciences;

    Abstract : With the emergence of industrialisation, the work-life balance has become a point of discussion in many industries, among which the aviation industry. Distortions in the work-life balance became especially apparent when 24/7 economies evolved, and industries made a transition to facilitate and serve these economies. READ MORE

  6. 10. Strength assessment of rig foundations for a sailing car carrier

    University essay from KTH/Lättkonstruktioner

    Author : Alfred Rapaport; [2020]
    Keywords : Naval Architecture; Solid Mechanics; Finite Element Analysis; Concept development; Sailing; Skeppsbyggnad; Hållfasthetslära; Finita elementmetoden; Konceptutveckling; Segling;

    Abstract : The wPCC project (wind powered car carrier) is carried out by Wallenius Marine, KTH Royal Institute of Technology and SSPA Sweden. By developing a car carrier mainly propelled by the wind, the emissions are estimated to be reduced by up to 90 %. This thesis deals with the structural aspects of the design. READ MORE
