21. Kinematics of the heart : strain and strain-rate using time-resolved three-dimensional phase contrast MRI
Sammanfattning : During the cardiac cycle, the myocardium (heart muscle) undergoes large elastic deformations as a consequence of the active muscle contraction along the muscle :fibers and their relaxation, respectively. A four-dimensional (4D) description (three spatial dimensions + time) of the kinematics of the myocardium would bring increased understanding of the mechanical properties of the heart and may be of interest in assessing regional myocardial function.

22. Finite Element Modeling of Contact Problems
Sammanfattning : Contact is the principal way load is transferred to a body. The study of stresses and deformations arising due to contact interaction of solid bodies is thus of paramount importance in many engineering applications. In this work, problems involving contact interactions are investigated using finite element modeling. LÄS MER
23. Microstructural finite element modeling of metals
Sammanfattning : The mechanical properties of metals have been investigated.This has been done by creating micromechanical models based onthe microstructural data available for the materials ofinterest. Thus, models containing a grain structure withappropriate constitutive equations have been created. LÄS MER

25. Finite element simulation of transformation plasticity in martensitic transformation
Sammanfattning : This study is concerned with the simulation of transformation plasticity in martensitic transformation. In the first paper the concept of a transformation plasticity strain is introduced from a phenomenological point of view. LÄS MER
