  1. 1. Tension and tradition : a study of late Iron Age spearheads around the Baltic Sea

    University dissertation from Stockholm : Stockholms universitet

    Author : Kristina Creutz; Bergljot Solberg; [2003]
    Keywords : HUMANIORA; HUMANITIES; HUMANITIES and RELIGION History and philosophy subjects Archaeology subjects Archaeology; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Arkeologiämnen Arkeologi; arkeologi; Archaeology;

    Abstract : This thesis discusses spearheads and individuals in Estonia, Latvia, eastern Sweden, Finland and western Russia during the 11th century. The source material consists of 335 spearheads of type M according to the typology of Petersen from 1919. READ MORE

  2. 2. A theory of experienced paradoxical tension in co-opetitive alliances

    University dissertation from Umeå : Umeå University

    Author : Tatbeeq Raza-Ullah; Maria Bengtsson; Malin Näsholm; Devi Gnyawali; Marianne Lewis; [2017]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; co-opetition; paradox; tension; cognitive difficulty; emotional ambivalence; management; balance; capability; performance; företagsekonomi; Business Studies;

    Abstract : Empirical research shows that co-opetition is a double-edged sword such that it can both help and hurt the achievement of desired performance outcomes. Despite the proliferation of co-opetitive alliances (i.e. READ MORE

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

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Per-Johan Gustafsson; [1985]
    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

  4. 4. In-plane tension behaviour of masonry

    University dissertation from Structural Engineering, Lund University

    Author : Miklos Molnar; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

    Abstract : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. READ MORE

  5. 5. Method for determination of the softening behaviour of wood and the applicability of a nonlinear fracture mechanics model

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Lars Boström; [1992]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture mechanics; wood; shear; fictitious crack model; tension; linear elastic fracture mechanics; softening; trä; materialegenskaper; hållfasthet; skjuvning; brottmekanik;

    Abstract : The thesis deals with determination of the post peak behaviour of wood in pure tension and pure shear. Furhermore, the "Fictitious Crack Model" (FCM), which is a nonlinear fracture mechanics model ; originally developed for description of crack propagation in concrete, is employed to demonstrate the advantages of non linear fracture mechanics.
