1. Modeling DNA Damage
Sammanfattning : In this thesis methods of computational chemistry have been used to examine DNA damaging processes initiated by ionizing radiation, free radicals, or Low-Energy Electrons (LEE). The computational chemistry method based on quantum mechanics that has been mainly used here is the Density Functional Theory (DFT). LÄS MER
2. Ductile damage modeling of the machining process
Sammanfattning : Machining processes are among the most common manufacturing processes for producing components used on a daily basis. It is a complex material removal process. Today, the research and development within the manufacturing industry is addressed by cost efficient numerical simulation strategies rather than by costly experimental procedures. LÄS MER
3. Plasticity and Damage Mechanics for Modeling Concrete Failure
Sammanfattning : Concrete structures exhibit strongly non-linear and complex mechanical behavior. Hence, they are nowadays often analyzed by means of the finite element method, whereby a realistic description of the material behavior is decisive for the validity of the results. LÄS MER
4. Infrared Laser Stimulation of Cerebral Cortex Cells - Aspects of Heating and Cellular Responses
Sammanfattning : The research of functional stimulation of neural tissue is of great interest within the field of clinical neuroscience to further develop new neural prosthetics. A technique which has gained increased interest during the last couple of years is the stimulation of nervous tissue using infrared laser light. LÄS MER
5. On the multiscale modeling of duplex stainless steel
Sammanfattning : This thesis deals with the modeling and simulation ofthe influence of the material substructure on the macroscopicmechanical properties of duplex stainless steel (DSS). Twosubscale levels and their interaction are considered: Grainstructure (mesoscale) and crystallographic structure (microscale). LÄS MER
