1. Mechano-sorptive Creep in Wood - Experimental Studies of the Influence of Material Properties
Abstract : Mechano-sorptive creep deformations appear when wood is loaded under varying moisture conditions. These creep deformations are known to be larger than the creep deformations under constant humidity conditions. The present thesis deals with mechano-sorptive creep in Norway spruce wood. READ MORE

2. Moisture-related properties of modified timber - an experimental study
Abstract : Wood has long traditions as a structural and building material. In those cases in which its natural features are not sufficient, chemical modification can eliminate some shortcomings. READ MORE

3. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour
Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

4. Assessment of existing concrete bridges : bending stiffness as a performance indicator
Abstract : Optimizing the use of existing civil reinforced concrete (RC) structures could be interpreted in such a way as to say that the capacity should be used and taken care of in an effective manner, both from a technical and economical point of view, keeping the safety in mind. Achieving this requires thorough understanding of the structure and also of the tools used for assessing current and future capacity and needs. READ MORE

5. On the quantification of healing in asphalt materials
Abstract : Asphalt materials exhibit self-healing characteristics. In order to evaluate the healing capabilities of these materials, numerous investigations are carried out by researchers. These investigations include various definitions of healing and mechanical test methods to quantify the extent of healing. READ MORE
