1. Exploring Biopolymer-Clay Nanocomposite Materials by Molecular Modelling
Sammanfattning : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. LÄS MER
2. Inelastic behavior of polymer composites
Sammanfattning : In the present thesis, the inelastic behavior of polymer composites is investigated. This investigation concerns three fields of study; time dependent behavior during the lifetime of the composite material, influence of micro-damage on its overall mechanical performance and development of chemical shrinkage strains during the curing process.

3. Micromechanical Behavior of Fiber Networks
Sammanfattning : Paper is used in a wide range of applications, each of which has specific requirements on mechanical and surface properties. The role of paper strength on paper performance is still not well understood. This work addresses the mechanical properties of paper by utilizing fiber network simulation and consists of two parts. LÄS MER
4. Non-linear behavior of bio-based composite : characterization and modeling
Sammanfattning : The development and application of bio-based composite materials have been frequently studied. Most of the work is done on quasi-static performance of these materials. However, these composites are highly non-linear therefore there is need for investigation of their viscelastic and viscoplastic behavior. LÄS MER
5. Modeling the behavior of inclusions in plastic deformation of steels
Sammanfattning : This doctoral thesis presents a modeling method fordemonstrating the behavior of inclusions and their surroundingmatrix during plastic deformation of steels.Inclusions are inescapable components of all steels. LÄS MER
