  3. 2. Mechanical and thermal buckling analysis of laminated composite plates

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Aswin Paremmal; Roopak Kuruthukulangara Varghese; [2023]
    Keywords : composite material; Mechanical Buckling; Buckling analysis;

    Abstract : Composite laminated structures have many application fields such as aerospace, civil, marine, bio medical, transportation, and mechanical engineering because of their convenience in handling, and very good mechanical properties. Buckling behavior of laminated composite plates subjected to plane loads is indeed an important consideration in the primary design of aircraft and launch vehicle components. READ MORE

  4. 3. Development of Damage Tolerance Methodology for Antenna Installations in Pressurized Aircraft

    University essay from KTH/Lättkonstruktioner

    Author : Jens Fagerberg; [2020]
    Keywords : ;

    Abstract : Modifying an aircraft must be done in a safe way such that the safe operation of the aircraft is not violated. Compliance must be shown towards certification and airworthiness regulations in order to install a modification and allow for commercial flight. Certification is a time-consuming process where damage tolerance analysis is a major part. READ MORE

  5. 4. Virtual characterization of composite materials for aero-engine components

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

    Author : Facundo Masari; [2020]
    Keywords : Composite; simulation; multiscale; modelling; UD; NCF; prepreg; aerospace; engine;

    Abstract : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. READ MORE

  6. 5. Fatigue life validation of aircraft materials

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Aashish Ramesh; Gaurav Kalkur; [2020]
    Keywords : Fatigue; Failure; High strength aluminium; High strength steel alloy; Al 7050-T7451; Al 7075-T6; AISI 4340 steels;

    Abstract : Fatigue is one of the critical design aspects with immense significance where thefatigue life of a material can be stated as the number of cycles that a componentcan withstand under a particular type of loading without failure. The design processhas to include fatigue analysis in order to predict failure due to fatigue. READ MORE
