  1. 1. Energy and Strength-based Criteria for Intralaminar Crack Growth in Regions with High Stress Gradients

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

    Author : Anish Niranjan Kulkarni; [2021]
    Keywords : Cross-ply composites; High crack density; Stress gradient; FEM; Stress analysis; Strain Energy Release Rate;

    Abstract : Cross-ply composite laminates can develop very high density of transverse cracks in the 90-layer under severe thermal and mechanical loading conditions. At such high crack densities, two adjacent cracks start to interact, and a stress gradient is created in the region between these cracks. READ MORE

  3. 2. Balancing between environmental impact and vibroacoustic performance for lightweight buildings

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Philip Carlsson; [2021]
    Keywords : Technology and Engineering;

    Abstract : Multi-storey buildings constructed in timber have become more common in recent years. A reason for this lies in the growing interest for sustainable building, where timber is seen as a particularly interesting alternative. READ MORE

  4. 3. 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

  5. 4. Robust repair methods of primary structures in composite

    University essay from Hållfasthetslära

    Author : Marcus Ramström; Mattias Gungner; [2013]
    Keywords : Composite; Repair; Scarf joint; Step joint; Fabric; Tape; FEM;

    Abstract : A request of material change when performing repairs on composite parts of SAABs JAS 39 Gripen has lead to the initiation of this project. The aim is to create a quicker and more robust repair method. READ MORE

  6. 5. Simulating a tensile test of a carbon fiber composite test specimen in ABAQUS

    University essay from Institutionen för teknik och samhälle

    Author : Ujjal kumar Saha; Adis Avdic; [2011]
    Keywords : composite material; ABAQUS simulation;

    Abstract : This work aims at providing a numerical tool for the efficient design of the multidirectional carbon fiber reinforced composite material by means of finite element simulations. Abaqus/ CAE v 6.9-1 software has been used to establish a 3D model for simulation of the tensile test on the composite specimen. READ MORE
