1. On error controlled atomistic-to-continuum modeling with application to graphene monolayers
Sammanfattning : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. LÄS MER
2. Modeling Residual Stress Fields in Soft Tissues : with Application to Human Arteries
Sammanfattning : Biomechanics or Mechanics of Biology comprises many different fields. This thesis deals with soft tissues or living tissues and the fact that these materials live in a pressurized environment. This means that an unloaded tissue may not be stress free. The stress in an unloaded body is usually called residual stress. LÄS MER
3. Mechanical Properties of Arteries : Identification and Application
Sammanfattning : In this Licentiate of Engineering thesis, a method is proposed that identifies the mechanical properties of arteries in vivo. The mechanical properties of an artery are linked to the development of cardiovascular diseases. LÄS MER
4. Soft Tissue Mechanics with Emphasis on Residual Stress Modeling
Sammanfattning : This thesis concerns residual stress modeling in soft living tissues. The word living means that the tissue interacts with surrounding organs and that it can change its internal properties to optimize its function. LÄS MER
5. Modelling the passive mechanical properties of arteries
Sammanfattning : This thesis concerns the modelling of passive mechanical properties of arteries. An artery is characterised by large nonlinear deformation, anisotropy and incompressibility. In addition, it is subjected to a residual stress when the applied load is removed. All this combined makes it complex to derive appropriate mechanical models. LÄS MER
