  4. 2. Phase field modeling of flaw-induced hydride precipitation kinetics in metals

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Claudio Nigro; Malmö University.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen embrittlement; finite element method; linear elastic fracture mechanics; finite volume method; phase transformation; phase field theory; hydride; TECHNOLOGY; TEKNIKVETENSKAP; Technology;

    Abstract : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. READ MORE

  5. 3. Characterisation and Some Statistical Aspects of Univariate and Multivariate Generalised Pareto Distributions

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Nader Tajvidi; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Göteborgs universitet.; Gothenburg University.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; generalised Pareto distribution; multivariate extreme value theory; multivariate Pareto distribution; small sample properties; Bartlett s correction; maximum likelihood; statistical computations; simulation AMS 1991 subject classification: 62F11; 62E20; 60F17; 65U05;

    Abstract : Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. A rather recent approach for modelling extreme events is the so called peak over threshold (POT) method. READ MORE

  7. 5. Weld Pool Simulations

    University dissertation from Göteborg : Department of Mathematical Sciences

    Author : Marcus Edstorp; Högskolan Väst.; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik; TECHNOLOGY Industrial engineering and economy Manufacturing engineering and work sciences Manufacturing engineering; TEKNIKVETENSKAP Industriell teknik och ekonomi Produktion och arbetsvetenskap Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Arc Welding; Weld Pool; Multiphysics Simulations; Moving Boundaries; Free Surfaces; Mesh Motion; Two-Phase Flow; Incompressible Flow; Electromagnetics; Finite Element Methods;

    Abstract : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.
