6. Moisture transport and fixation in porous materials at high moisture levels
Sammanfattning : The work presented in this thesis focuses on developing methods of measuring moisture properties at high moisture levels. Paper I deal with a new method of measuring moisture diffusivity at high moisture levels. Papers II to IV present methods of measuring moisture storage capacity as well as results from such measurements. LÄS MER
7. Moisture Balance in Painted Wood Panelling
Sammanfattning : Over the last years thousands of houses have been damaged by wood rot in the exterior wood panelling due to excessive moisture conditions. This thesis is about moisture conditions and the way moisture enters and exits painted wood panelling structures. LÄS MER
8. Moisture Transport and Moisture-Induced Distortions in Timber - an Experimental and Numerical Study
Sammanfattning : Timber products subjected to climatic variations commonly display moisture-induced distortions that can lead to serious problems for end-users. The aim of the thesis, which consists of an extended summary and six appended papers, was to investigate the potential of using the gluing technique suggested here for dealing with problems of moisture-induced distortions and developing the heat and mass transfer models which such distortion analyses require.

9. Numerical Analysis of Moisture-Related Distortion in Sawn Timber
Sammanfattning : A 3D theory for the numerical simulation of deformations and stresses in wood during moisture variation is described. The constitutive model employed assumes the total strain rate to be the sum of the elastic strain rate, the moisture-induced strain rate, the mechano-sorption strain rate and the creep strain rate.

10. Investigations on moisture damage-related behaviour of bituminous materials
Sammanfattning : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. LÄS MER
