2. 1. Physics of Aftershocks in the South Iceland Seismic Zone : Insights into the earthquake process from statistics and numerical modelling of aftershock sequences

   Author : Mattias Lindman; Roland Roberts; Björn Lund; David Marsan; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake processes; Aftershocks; Physics of aftershocks; Omori law; Postseismic processes; Pore pressure diffusion; Poroelasticity; Statistical seismology; Self-organised criticality; Interevent time distributions; Waiting time distributions; Geophysics; Geofysik;

   Abstract : In seismology, an important goal is to attain a better understanding of the earthquake process. In this study of the physics of aftershock generation, I couple statistical analysis with modelling of physical processes in the postseismic period. READ MORE

4. 2. Multi-scale modeling and finite element simulation of diffusion in porous media

   Author : Nele Pollmann; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro-Mechanical Coupling; Fractured Rock; Poroelasticity; Three-Phase Concrete; Computational Homogenization;

   Abstract : Porous media comprise a large range of natural and industrial materials and are typically complex on multiple length scales. At lower (micro-scopic) length scales, such media consist of a solid skeleton and fluid-filled pores in between. READ MORE

   Abstract : Thin structures are used in a wide range of engineering applications. The subject of this thesis is the derivation of approximate equations for the dynamics of thin plates and shells using series expansion methods. READ MORE

7. 5. On Error-Controlled Numerical Model Reduction for Linear Transient FE² Analysis

   Author : Fredrik Ekre; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; computational homogenization; error estimation; model reduction;

   Abstract : Multiscale modeling is of high interest in the engineering community due to its ability to capture the overall response, while still accounting for processes and structures on underlying fine scales. One standard approach to multiscale modeling is the so-called FE² procedure, where the classic constitutive relation is replaced by a boundary value problem on a Representative Volume Element (RVE) comprising the underlying microscale features.
