Resumen

SALINAS, C. H.; CHAVEZ, C. A.; GATICA, Y.  y  ANANIAS, R.A.. Simulation of wood drying stresses using CVFEM. Lat. Am. appl. res. [online]. 2011, vol.41, n.1, pp. 23-30. ISSN 0327-0793.

The drying of solid wood and associated stresses were simulated by applying the Control Volume Finite Element Method (CVFEM) to a transversal section of solid wood on the radial/tangential plane. The transport of moisture content and stresses produced by its gradients associated with the phenomena of shrinkage and mechanical sorption were modeled simultaneously. In particular, we used a CVFEM program (Fortran 90) that allows integrating a differential equation of non-linear transient diffusion, defining triangular finite elements with linear interpolation of the independent variable within itself. The model was validated by comparing the experimental and analytical results available in the specialized literature. Finally, we showed the original results of the simulation applied to the drying of aspen wood(Populus tremuloides) at three drying temperatures.
