  1. 1. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses

    Författare :Per-Johan Gustafsson; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; corners; test-specimens; strength; tension; fracture mechanics; strain localization; size-effect; flexural strength; LEFM; fictitious crack model; Weibull; FEM; pipes; shear strength; concrete; diagonal tension;

    Sammanfattning : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. LÄS MER

    Sammanfattning : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. LÄS MER

  4. 4. Strength Criteria on Grouting Agents for Hard Rock- Laboratory studies performed on gelling liquid and cementitious grout

    Författare :Magnus Axelsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory study; colloidal silica; rheology; shear strength; Grout; erosion; strength; cement; yield stress; silica sol;

    Sammanfattning : Grouting is usually successful in excavations at moderate depths and groundwater inflow. At great depths, in post-grouting or in rock with a large inflow of water, grouting is more problematic due to the forces from groundwater. LÄS MER

  5. 5. Analytical and numerical approaches to estimate peak shear strength of rock joints

    Författare :Francisco Ríos Bayona; Stefan Larsson; Fredrik Johansson; Diego Mas Ivars; José Muralha; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Rock joint; Shear strength; Failure criterion; Numerical shear tests; Bergsprickor; Skjuvhållfasthet; Brottkriterium; Numeriska skjuvförsök; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. LÄS MER
