  1. 1. Timber Concrete Composite floors with Cross Laminated Timber - Structural behavior & Design

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Albin Forsberg; Filip Farbäck; [2020]
    Keywords : timber concrete composite; TCC; floors; cross-laminated timber; CLT; structural behavior; design methods; Gamma method; Equivalent gamma method; Extended gamma method; RFEM; first natural frequency; serviceability limit state; ultimate limit state; Technology and Engineering;

    Abstract : På grund av den ökade miljö- och klimatmedvetenheten har övergången till förnybara material påskyndats, och detsamma gäller intresset för träbyggande. Med att bygga högt i trä kommer dock ett flertal konstruktionsmässiga utmaningar, där en av utmaningarna är dynamik på grund av träets låga egenvikt jämfört med andra mer konventionella byggnadsmaterial.

  3. 2. 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. 3. Study of delamination of composite hat skin stringer interface failure

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Rajkumar Rajamanickam; [2019]
    Keywords : Delamination; Cohesive Zone Model; Skin-Stringer; Composite modelling; ABAQUS; Interface failure;

    Abstract : The use of composite materials brought a tremendous breakthrough in the scientific world of aerospace engineering. The lack of understanding of the failure of composite materials can be disastrous. Composite laminated structures need to be thoroughly studied and investigated in the design stage. READ MORE

  5. 4. Simulation of Delamination Migration in Laminated Composite Structures - An Approach Combining Extended Finite Elements and a Cohesive Zone Model

    University essay from Lunds universitet/Hållfasthetslära

    Author : Viktor Björklund; [2018]
    Keywords : Crack propagation modeling; Fiber-reinforced polymer; Laminated composites; FRP; CFRP; Cohesive zone model; CZM; Delamination migration; FEM; XFEM; Fracture mechanics; Progressive damage modeling; Surface-based cohesive behaviour; Technology and Engineering;

    Abstract : Fiber-reinforced polymer matrix composites are being used increasingly in lightweight applications where high strength and stiffness is required. One of the main challenges with designing components from such materials is to predict the ultimate strength and behaviour of the structure. READ MORE

  6. 5. Polyimide thin-ply composite

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

    Author : KHALID MOUANE; [2018]
    Keywords : Polyimide; thin-ply; microcracking; curing stress; mechanical loading;

    Abstract : Mechanical performance of composite structures is influenced by the accumulation of damage from the manufacturing process and throughout the whole service life. For instance, an aircraft is subjected to a combination of mechanical loading and the thermo-oxidative environment from the take-off to the landing. READ MORE
