16. Plasticity Driven Damage and Void Growth
Sammanfattning : Plasticity induced damage evolution is considered using a thermodynamical approach. Different postulates on how to include the effects of damage in the constitutive equations have been studied. The results reveal that a mapping, similar to that of the stress, of both the kinematic and isotropic hardening variables is to be preferred. LÄS MER
17. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure
Sammanfattning : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. LÄS MER
18. Biomarkers for DNA damage in human biomonitoring
Sammanfattning : Genomic DNA in humans is constantly exposed to different kinds of damage. Therefore, it is desirable to implement methods for detecting and measuring of inflicted body burden. Human biomonitoring (HBM) can here be a useful tool as a link between environmental exposure and disease outcome. LÄS MER
19. Radiation response in human cells : DNA damage formation, repair and signaling
Sammanfattning : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. LÄS MER
20. On numerical analyses of woven composite laminates : Homogenization, damage and fracture
Sammanfattning : This dissertation analyzes various mechanical properties of textile reinforced composite laminates.The dissertation is based on a total of six published works, which are essentially numerical, although experimental elements are available. LÄS MER
