  1. 1. Fatigue Analysis of a Lively Footbridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Kristi Bila; [2019]
    Keywords : ;

    Abstract : The commitment of building aesthetic bridges made of stiff materials results in theconstruction of slender structures highly susceptible to dynamic loading. In the caseof footbridges located over a highly trafficked highway, such dynamic loads maybe the aerodynamic pressure induced by the heavy trucks passing underneath thestructure and the pedestrian loading involving a pedestrian running and jumping.

  4. 4. 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
