  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. 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
