  1. 16. Numerical methods for glacial isostatic adjustment  models

    University essay from Institutionen för informationsteknologi

    Author : Juan Carlos Araujo-Cabarcas; [2013]
    Keywords : ;

    Abstract : Nordic countries experience post-glacial rebound, a movement where geographical contours slowly change elevation with respect to the mean sea level. The glacial isostatic adjustment (GIA) model aims to explain the phenomena, which combined with seismic data allows geoscientists to reconstruct elastic coefficients and viscosities of the Earth's lithosphere and upper mantle.

  3. 17. Effect of material grade on fatigue strength and residual stresses in high strength steel welds

    University essay from KTH/Lättkonstruktioner

    Author : Wasim Asgher; [2012]
    Keywords : Fatigue Strength; Fillet Welded Joints; Effective Notch Method; Residual Stress Simulation.;

    Abstract : This thesis work is concerned with effect of material grade on fatigue strength of welded joints. Fatigue strength evaluation of welded joints in as welded and post weld treated condition was carried out with effective notch method. Results of peak stress method have also been compared with those of effective notch method for as welded joints. READ MORE

  4. 18. Estimating of Work Hardening in Bent Sheet Metal Products at an Early Stage of Virtual Product Development

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Rokneddin Azizi; Hossein Amiryousefi; [2012]
    Keywords : Forming simulation; Testing simulation; Work Hardening; Finite Element Method; Steel sheet metal product development ;

    Abstract : The thesis has two aims: firstly, to investigate the influence of work hardening due to forming simulation on test simulation. The investigated question was also: Is it worth the effort to include work hardening effect into test simulation? The second aim was, to propose a quicker method to estimate work hardening without forming simulation. READ MORE

  5. 19. Dynamic analysis of soil-steel composite bridges for high speed railway traffic : Case study of a bridge in Märsta, using field measurements and FE-analysis

    University essay from KTH/Bro- och stålbyggnad

    Author : Peyman Mellat; [2012]
    Keywords : Soil-Steel Composite Bridge; Flexible Corrugated Steel Culvert; Structural Dynamics; Acceleration; High-Speed Trains; Field Measurement; FEM;

    Abstract : Soil-steel composite bridge refers to structures where a buried flexible corrugated steel pipe works in composite action with the surrounding soil. These structures are being increasingly used in road and railway projects as an alternative to standard type bridges, e.g. short- and medium span concrete beam- and portal frame bridges. READ MORE

  6. 20. FEM Modelling of Piled Raft Foundations in Two and Three Dimensions

    University essay from Lunds universitet/Geoteknik

    Author : André Ryltenius; [2011]
    Keywords : Technology and Engineering;

    Abstract : In conventional design of pile foundations, all loads are taken by the piles, i.e. the contact pressure between the raft and the soil is neglected. In the last decades geotechnical engineers have started to take this pressure into account in design of pile foundation. READ MORE
