12. Cracking in Reinforced Concrete Structures Due to Imposed Deformations
Abstract : This thesis is concerned with modeling of the cracking process in reinforced concrete due to imposed deformations. Cracking is investigated both at early ages, during hydration, and at mature age when the final properties of the concrete are reached. READ MORE

13. Microstructure model for Ti-6Al-4V used in simulation of additive manufacturing
Abstract : This thesis is devoted to microstructure modelling of Ti-6Al-4V. The microstructure and the mechanical properties of titanium alloys are highly dependent on the temperature history experienced by the material. The developed microstructure model accounts for thermaldriving forces and is applicable for general temperature histories. READ MORE

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

15. Numerical Model Reduction and Error Control for Computational Homogenization of Transient Problems
Abstract : Multiscale modeling is a class of methods useful for numerical simulation of mechanics, in particular, when the microstructure of a material is of importance. The main advantage is the ability to capture the overall response, and, at the same time, account for processes and structures on the underlying fine scales. READ MORE
