  1. 16. Bucket-soil interaction for wheel loaders : An application of the Discrete Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Felix Henriksson; Joanna Minta; [2016]
    Keywords : Discrete element method; multibody system; wheel loader; soil-tool interaction; co-simulation interval; gravel pile; collision detection interval; normal stiffness;

    Abstract : Wheel loaders are fundamental construction equipment to assist handling of bulk material e.g. gravel and stones. During digging operations, it withstands forces that are both large and very complicated to predict. READ MORE

  3. 17. Micromechanical Numeric Investigation of Fiber Bonds in 3D Network Structures.

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : YAĞIZ AZİZOĞLU; [2014]
    Keywords : Finite element; strength additive; 3D model; fiber network model; contact stiffness; paper strength; AFM; fiber adhesion.;

    Abstract : In manufacturing of paper and paperboard, optimized fiber usage has crucial importance for process efficiency and profitability. Dry strength of paper is one of the important quality criteria, which can be improved by adding dry strength additive that affect fiber to fiber bonding. READ MORE

  4. 18. Shear Strength of Reinforced Concrete Beams subjected to Blast Loading : Non-linear Dynamic Analysis

    University essay from KTH/Bro- och stålbyggnad

    Author : Abbas Zangeneh Kamali; [2012]
    Keywords : Non-linear finite element analysis; Shear Strength; Reinforced Concrete; Normal Strength Concrete; Blast loading; Explicit Dynamic analysis; Design codes;

    Abstract : The experimental investigations performed on the behaviour of reinforce concrete elements subjected to blast loading have revealed that the shear mechanisms and ductility play important roles in the overall response and failure mode of such structures. The main aim of this master thesis is to study the possibility of using finite element method as a tool for predicting the dynamic response of blast loaded reinforced concrete beams and evaluation of their shear strength.

  5. 19. Controlling parameters for normal and shear behaviour of rock fractures-a study of direct shear test data from SKB

    University essay from KTH/Jord- och bergmekanik

    Author : Hanna Melin; [2012]
    Keywords : open fracture; shear strength; mechanical parameters; friction angle; roughness;

    Abstract : The deep mining and civil engineering industry need to perform rock stability analyses during excavation projects. The stability is mainly controlled by the shear strength of the rock fractures, which are the weakest point of the rock mass. In turn, the shear strength is governed by the mechanical properties of the fractures. READ MORE

  6. 20. Analysis of Block Stability and Evaluating Stiffness Properties

    University essay from KTH/Byggvetenskap

    Author : Syed Bahadur Shah Shah; [2011]
    Keywords : Block stability; Joint Stiffness; Stiffness ratio; Clamping forces; Pullout forces;

    Abstract : Block stability is common and has to be studied in detail for designing tunnels. Stability of block depends upon the shape and size of the blocks, stresses around the block and factors such as clamping forces and the ratio between joint stiffness. These factors are studied in detail and are the main objective of this thesis. READ MORE
