  1. 1. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Simon Stahlin; [2019]
    Keywords : composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

    Abstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

  3. 2. Early assessment of composite structures : Framework to analyse the potential of fibre reinforced composites in a structure subjected to multiple load case

    University essay from KTH/Lättkonstruktioner; KTH/Hållfasthetslära (Avd.)

    Author : Srikanth Ananthasubramanian; Priyank Gupta; [2018]
    Keywords : MATLAB; Fibre Reinforced Plastics; finite-element; laminate design; classical laminate theory.;

    Abstract : To meet the need of lightweight chassis in the near future, a technological step of introducing anisotropic materials like Carbon Fibre Reinforced Plastics (CFRP) in structural parts of cars is a possible way ahead. Though there are commercially available tools to find suitability of Fibre Reinforced Plastics (FRPs) and their orientations, they depend on numerical optimization and complexity increases with the size of the model.

  4. 3. Failure Modeling of Curved Composite Beams : Numerical Modeling of Failure Onset and Propagation in L-Profile Beams

    University essay from KTH/Lättkonstruktioner

    Author : Suhas Gururaj Shetty; [2018]
    Keywords : ;

    Abstract : The high strength/stiffness-to-weight ratio that composite materials exhibit has led to the utilization of composites as alternative to traditional materials in weight-critical applications. However, the highly anisotropic nature of composites renders the strength prediction under complex loading challenging. READ MORE

  5. 4. Linkages between the Chinese stock market and the macroeconomic climate in the U.S. and EU

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Gabriel Ekman; Petter Månsby; [2018]
    Keywords : VECM; Impulse Responses; Variance Decomposition; Chinese stock market; macroeconomic linkages; finacial integration; Business and Economics;

    Abstract : The purpose of this paper is to examine the relationship between investments in the Chinese stock market and shocks to the macroeconomic climate in the U.S. and in the EU. READ MORE

  6. 5. 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
