1. 1. Adaptive variational multiscale methods

   Författare :Axel Målqvist; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite element method; Galerkin; duality; a posteriori error estimation; adaptivity; variational multiscale method; mixed formulation; multi-physics; oil reservoir simulation; finite element method;

   Sammanfattning : In this thesis we present a new adaptive multiscale method for solving elliptic partial differential equations. The method is based on numerical solution of decoupled local fine scale problems on patches. LÄS MER

3. 2. Computational modeling of polycrystals using gradient crystal plasticity

   Författare :Mikkel Grymer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel algorithms; crystal plasticity; dual mixed finite element method; gradient hardening; grain modeling;

   Sammanfattning : This thesis treats the modeling of grain size dependence inmicrostructure models of metals. It is shown how gradient hardening, in a thermodynamically consistent fashion, can be included into a crystal plasticity model, which is used as the constitutive model in each grain of the polycrystal.
