11. On Crack Dynamics in Brittle Heterogeneous Materials
Sammanfattning : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. LÄS MER
12. 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
13. Moisture-Induced Strains and Stresses in Wood
Sammanfattning : To design safe, reliable and durable timber structures subjected to varying natural outdoor or indoor climates, understanding the long-term behavior of wood when mechanically loaded or restrained to deform is crucial. The present thesis focuses on the numerical modeling of the long-term mechanical behavior of wood. LÄS MER
14. Biomechanical Analysis of Stress and Stiffness of New Load-Bearing Implants
Sammanfattning : Medical implants are essential products for saving lives and improving life quality. Nowadays, the demand for implants, especially biocompatible and personalized ones, is increasing rapidly to deal with factors like congenital malformations, aging, and increasing prevalence of cancer.
