  2. 1. Wellbore stability analysis based on a new true-triaxial failure criterion

    Author : Adel Al-Ajmi; Robert Zimmerman; Bernt Aadnoy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failure criteria; Mogi failure criterion; intermediate principal stress; polyaxial test data; wellbore stability; Geoengineering and mining engineering; Geoteknik och gruvteknik;

    Abstract : A main aspect of wellbore stability analysis is the selection of an appropriate rock failure criterion. The most commonly used criterion for brittle failure of rocks is the Mohr-Coulomb criterion. READ MORE

  4. 2. Shear walls with double plasterboards : evalutation of design models

    Author : Tomas Filipsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis presents a part of the ECSC-project Development of dry composite construction systems based on steel in residential application that focus on design recommendations for stabilizing buildings by using shear resistance in the walls. The existing design method suggested and used by the Swedish plasterboard manufacturer Gyproc AB is considered as a bit conservative and it does not consider double plasterboards properly. READ MORE

  5. 3. On Uncertainty and Data Worth in Decision Analysis for Contaminated Land
