1. Damage Tolerance of Impacted Composite Sandwich Structures
Abstract : This thesis deals with damage tolerance of impacted sandwich structures for load bearing applications. Composite sandwich structures find wide application as lightweight solutions in aerospace components, since weight reduction and less fuel emissions are primary concerns for aircraft manufactures.

2. Ductile damage modeling of the machining process
Abstract : 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. READ MORE

3. Towards frost damage prediction in asphaltic pavements
Abstract : Roads are subjected to mechanical loads from the traffic as well as deteriorating mechanisms originating from the surrounding environment and climate. The damage arising is particularly severe during the winter season, when for example raveling, pot holes and cracks can emerge on the surfaces of asphaltic roads. READ MORE

4. Modeling DNA Damage
Abstract : 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). READ MORE

5. Plasticity and Damage Mechanics for Modeling Concrete Failure
Abstract : 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. READ MORE
