A multiscale modelling approach aided by X-ray techniques to deepen the understanding of the effect of climate change on the hygromechanical behaviour of wood

Climate change has shown to alter the mechanical properties of wood. This suggest an alteration of the hygromechanical behaviour, behaviour that by itself is not fully elucidated yet. The deeper understanding of the hygromechanics of wood is important in the correct prediction and interpretation of drying and long-term behaviour of this material. In this light, […]

Theoretical study of lignin swelling in atomistic details

TREESEARCH

In this project vi use molecular dynamics (MD) simulations to investigate hygroscopic properties of various lignins. Our hope is that structure and dynamics on the atomistic level of details will complement existing macromechanical models. The goal is to test existing atomistic models of lignin subject to its interactions with water. The output of the project

Microscopic computed tomography aided finite element modelling of wood

TREESEARCH

Laboratory X-ray tube-based microscopic computed tomography (XµCT) aided finite element (FE) modelling considers XµCT data to characterize key engineering properties needed for modelling of material behavior. The method includes steps such as XµCT scanning, segmentation, meshing, and fiber reconstruction and can be supported by techniques such as digital image correlation and digital volume correlation. At

Multi scale modeling of the delignification kinetics during kraft cooking

TREESEARCH

The kraft process is today the dominant industrial technology for the production of pulp from wood.In this process, wood chips are boiled with chemicals in order to dissolve lignin, hemicellulose andextractives. The process itself contains several complex mass transport mechanisms, where thechemicals are to be transported into the wood chip and then further into the

Material properties of wooden material: scale effect

TREESEARCH

The use of wood as a building material because of its efficiency, sustainability, and durability is increasing. Wood is a renewable resource, it has low carbon impact and low embodied energy. The amount of energy needed for producing wood products is much less than comparable products made from other materials. In spite of its common
