  1. 11. 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

  3. 12. Settlement calculation for lime/cement column improved clay : Analytical and numerical analyses related to a case study

    University essay from KTH/Jord- och bergmekanik

    Author : Hulumtaye Kefyalew Yederulh; [2018]
    Keywords : LCC; deep mixing; consolidation settlement; rate of consolidation; numerical analysis; analytical analysis; field measurement.; KC-pelare; djupstabilisering; konsolideringssättningar; konsolideringsgrad; numerisk analys; analytisk analys; fältmätningar;

    Abstract : The dry deep mixing method is widely used to improve a soft clay soil to increase the shear strength as well as to reduce the time for consolidation. It is a mechanical mixing process that makes parts of the soil stiffer than its original strength. It is mainly applicable to soft clay or peat soil. READ MORE

  4. 13. Terrain machine learning : A predictive method for estimating terrain model parameters using simulated sensors, vehicle and terrain

    University essay from Umeå universitet/Institutionen för fysik

    Author : Viktor Wiberg; [2018]
    Keywords : machine learning; terrain-vehicle interaction; discrete element method; multivariate statistics; terrain trafficability;

    Abstract : Predicting terrain trafficability of deformable terrain is a difficult task with applications in e.g, forestry, agriculture, exploratory missions. The currently used techniques are neither practical, efficient, nor sufficiently accurate and inadequate for certain soil types. READ MORE

  5. 14. Additive manufacturing : Optimization of process parameters for fused filament fabrication

    University essay from KTH/Lättkonstruktioner

    Author : Vishal Hayagrivan; [2018]
    Keywords : Additive manufacturing AM ; Fused filament fabrication FFF ; Fused deposition modeling FDM ; Process parameters; Optimization; Tool path reversing; GCode parser; Stiffness prediction; Strength prediction; Inter-layer bonding;

    Abstract : An obstacle to the wide spread use of additive manufacturing (AM) is the difficulty in estimating the effects of process parameters on the mechanical properties of the manufactured part. The complex relationship between the geometry, parameters and mechanical properties makes it impractical to derive an analytical relationship and calls for the use of a numerical model. READ MORE

  6. 15. Testing of CLT-Concrete Composite decks

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Joakim Thilén; [2017]
    Keywords : Notch; Adhesive; Composite Decks; Deflection; Gamma-method; CLT; TCC; Technology and Engineering;

    Abstract : When massive timber decks are used in buildings the design is often regulated by serviceability limit state (SLS), mainly the vibration criteria. To decrease the risk for vibrations of a deck the bending stiffness needs to be increased. READ MORE
