Microscopic computed tomography aided finite element modelling of wood

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

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 …
