|Summary||In this work, a comprehensive 1-D object-oriented finite element processing model for oriented strand board (OSB) wood composites has been developed. The model consists of modules of heat and mass transfer, resin cure and wood compaction. Predicted transient temperature and internal steam pressure profiles for different mat initial moisture contents and densities are compared with measurements from instrumented mats. Furthermore, predicted vertical density profile is compared to results obtained from x-ray scans. In general, the model captures the trends observed in practice and therefore can be a valuable tool for the OSB producers to understand and improve manufacturing processes.
