16. Modeling of coupled thermoplasticity at finite strains
Sammanfattning : In this thesis, models for simulation of inelastic phenomena, such as plastic anisotropy, texture evolution, void growth and phase transformation are presented. Special emphasized is put on the modeling of heat generation due to plastic work. All models are formulated within a thermodynamic framework that allows large deformations. LÄS MER
17. Effect of water contamination on the diffused content of hydrogen under stress in AISI-52100 bearing steel
Sammanfattning : Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel.

18. Strain-assisted corrosion cracking and growth rate inhibitors
Sammanfattning : A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. LÄS MER
19. Drum sound from floor coverings - objective and subjective assessment
Sammanfattning : Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound.

20. Modeling and Performance of Gas Turbine Cycles with Various Means of Blade Cooling
Sammanfattning : A method for simulating the cooled gas turbine is demonstrated. Based on equations and other knowledge found in the literature, a first-law thermodynamic, non-dimensional model is established and implemented in the equation-solving, programmable software IPSEpro. LÄS MER
