  2. 6. Multiscale Constitutive Modeling of Heterogeneous Engineering Materials

    Author : Johan Jansson; Kent Salomonsson; Jakob Olofsson; Julian J. Rimoli; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This work deals with different methods used to determine heterogeneous constitutive model parameters for macro-scale finite element models, based on microstructural variations, caused by the manufacturing process. These methods could be applied to decrease modeling errors associated with the material behavior, improving the predictive capabilities of structural analyses in simulation-driven industrial product development.

  4. 7. The Pursuit of Relevance : Studies on the Relationships between Accounting and Users

    Author : Johan Graaf; Matti Skoog; Roland Almqvist; John Holland; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accounting; Information; Relevance; Financial analysis; Social and Institutional Practice; Capital Markets; Sell-side; Analyst; Broker; Equity sales; Investment recommendations; företagsekonomi; Business Administration;

    Abstract : Relevance has become one of the key priorities for accounting policy, and implies that accounting should have an impact on the economic decision-making of accounting users. Despite the increased importance given to users, however, little is known concerning the properties of such relevance in practice. READ MORE

  5. 8. Fracture mechanics models for fatigue in concrete structures

    Author : Kent Gylltoft; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis deals with the application of fracture mechanics to model monotonic and cyclic loading of reinforced concrete structures. The main features of the work are: - Constitutive modelling based on fracture mechanics - Numerical studies of the models in various applications - Experimental studies to check the models and to determine material parameters The fracture mechanics models are formulated on a constitutive level.

  6. 9. Laboring Through Uncertainty : an ethnography of the Chinese state, labor NGOs, and development

    Author : Darcy Pan; Johan Lindquist; Anette Nyqvist; Stephan Feuchtwang; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; uncertainty; intimacy; complicity; mingan; secrecy; state; NGO; socialantropologi; Social Anthropology;

    Abstract : This study sets out to understand how international development projects supporting labor activism work in contemporary China. It focuses on the lived experiences of and relationships among a group of grassroots⁠ labor NGOs in the province of Guangdong, South China; intermediary NGOs in Hong Kong; and Western funding agencies that try to bring about social change in postsocialist China where the political climate is still highly restrictive and the limits of the state’s tolerance for activism are ambiguous and uncertain.

  7. 10. Degradation of thermo-elastic properties in damaged composite laminates : a theoretical study

    Author : Peter Lundmark; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : Fiber composites are today widely used in different load carrying structures. The main reason is their high stiffness and strength to weight ratio. Due to these specific properties they are frequently used in car, marine and space industry. READ MORE
