  2. 1. Metal film growth on weakly-interacting substrates : Multiscale modeling

    Author : Víctor Gervilla Palomar; Kostas Sarakinos; Georgios Almyras; Davide Giuseppe Sangiovanni; Michael Tringides; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. READ MORE

  4. 2. Linear models for multiscale materials simulations : Towards a seamless linking of electronic and atomistic models for complex metal oxides

    Author : Akshay Krishna Ammothum Kandy; Peter Broqvist; Jolla Kullgren; Eddie Wadbro; Ben Hourahine; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Force fields; Electronic structure calculations; CCS; DFTB; CCS Q; repulsive fitting; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Multiscale modelling approaches, connecting data from electronic structure calculations all the way towards engineering continuum models, have become an important ingredient in modern materials science. Materials modelling in a broader sense is already amply used to address complex chemical problems in academic science, but also in many industrial sectors. READ MORE

  5. 3. 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.
