1. Quasi-instantaneous and Long-term Deformations of High-Performance Concrete with Some Related Properties
Abstract : This report outlines an experimental and numerical study on quasi-instantaneous and long-term deformations of High-Performance Concrete, HPC, with some related properties. For this purpose about two hundred small cylinders and about one thousand cubes of eight types of HPC were cast. The age at loading varied between 18h and 28 days. READ MORE

2. 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

3. Simulation of additive manufacturing using a mechanism based plasticity model
Abstract : This thesis presents finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling of alloy 625 and alloy 718. In recent years, there has been an increasing interest in AM and there has been a dramatic increase in publications in the field. READ MORE

4. Multiscale modeling of dynamic recrystallization
Abstract : During thermomechanical processing of metals, changes occur in the microstructure of the material which affect its macroscopic properties. By understanding these transformations in the microstructure, it becomes possible to design the processes in a way which yields the desired properties in the finished product. READ MORE
