  1. 6. Network Modelling for Evaluation of Mechanical Properties of Cellulose Fibre Fluff

    Detta är en avhandling från Susanne Heyden, Division of Structural Mechanics, Box 118, 221 00 Lund, Sweden

    Författare :Susanne Heyden; Lund University.; Lunds universitet.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; fracture; fibres; computer simulation; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : A network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. LÄS MER

  2. 7. Vibrations in a Built Environment : Prediction and Reduction

    Detta är en avhandling från Susanne Heyden, Division of Structural Mechanics, Box 118, 221 00 Lund, Sweden

    Författare :Peter Persson; Lund University.; Lunds universitet.; [2016-04-19]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration reduction; finite element method; coupled problems; vibration measurements; wave propagation; ground vibration; soil dynamics; wave barrier; shaped landscape; soil stabilisation; liquid-filled pipes; model order reduction;

    Sammanfattning : Vibrations in a built environment can exceed the requirements for sensitive equipment in a building or can cause annoyance to residents. Hence, there is often a need for reducing such vibrations. The vibrations can originate from ambient sources such as motorway traffic, or from internal sources such as people walking inside the building. LÄS MER

  3. 8. Numerical modelling of geomaterials at failure

    Detta är en avhandling från Department of Construction Sciences, Lund University

    Författare :Alex Spetz; Lund University.; Lunds universitet.; [2019-09-19]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil-structure interaction; soil plasticity; phase-field fracture model; compression driven fractures; artificial rock; porous rock; finite element analysis; isogeometric analysis; NURBS; numerical methods;

    Sammanfattning : Geotechnical engineering is the science dealing with mechanics of soils and rocks and its engineering applications. Geotechnical engineering projects vary in a wide range, from evaluation of the stability of natural slopes and man-made soil deposits, to the design of earthworks and foundations. LÄS MER

  4. 9. Soil Modification By Adding Small Amounts of Soil Stabilizers Impact of Portland Cement and the Industrial By-Product Petrit T

    Detta är en avhandling från Luleå University of Technology

    Författare :Wathiq Al-Jabban; Luleå tekniska universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : This licentiate thesis presents results of laboratory experiments regarding the effectiveness of adding small amounts of binders in order to modify and improve the mechanical performance of low organic clayey silt soil. Two types of binders have been used i.e. cement and an industrial by-product named Petrit T. LÄS MER

    Sammanfattning : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. LÄS MER
