  2. 1. Undrained shear strength in clay slopes - Influence of stress conditions. A model and field test study

    Author : Hjördis Löfroth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; preconsolidation pressure; piezocone test; slope; model test; consolidation; horizontal stress; clay; undrained shear strength; direct simple shear test; field vane test; field test;

    Abstract : To counteract natural hazards such as landslides, current methods for evaluation of soil properties as a mean for determining the safety level of natural slopes need to be refined. The empirical relationships used for estimation of the undrained shear strength from piezocone and field vane test are based on the stress conditions valid for horizontal ground and normally consolidated or slightly overconsolidated soil.

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

    Author : Per-Johan Gustafsson; Institutioner vid LTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. The strength of glulam beams with holes - A probabilistic fracture mechanics method and experimental tests

    Author : Henrik Danielsson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture mechanics; Weibull; design; test; strength; stress; glulam; hole; probabilistic fracture mechanics.;

    Abstract : This thesis deals with experimental tests and methods for strength analysis of glulam beams with holes. Test results and methods for strength analysis available in literature are compiled and discussed. The methods considered comprise both code strength design methods and more general methods for strength analysis. READ MORE

  7. 5. High strength steel : local buckling and residual stresses

    Author : Mattias Clarin; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : High strength steel provide designers with the possibility of creating more slender and weight efficient structures than would be possible if using steels with lower strength. To be able to do this, a structural designer needs updated and validated codes as aid in their work. READ MORE
