Two-dimensional wood drying stress simulation using control-volume mixed finite element methods (cvfem)
The work was aimed at simulating two-dimensional wood drying stress using the control-volume finite element method (CVFEM). Stress/strain was modeled by moisture content gradients regarding shrinkage and mechanical sorption in a cross-section of wood. CVFEM was implemented with triangular finite ele...

| description |
The work was aimed at simulating two-dimensional wood drying stress using the control-volume finite element method (CVFEM). Stress/strain was modeled by moisture content gradients regarding shrinkage and mechanical sorption in a cross-section of wood. CVFEM was implemented with triangular finite elements and lineal interpolation of the independent variable which were programmed in Fortran 90 language. The model was validated by contrasting results with similar ones available in the specialised literature. The present model’s results came from isothermal (20ºC) drying of quaking aspen (Populus tremuloides): two-dimensional distribution of stress/strain and water content, 40, 80, 130, 190 and 260 hour drying time and evolution of normal stress (2.5 and lt;σ͓ ͓ and lt; 1.2, MPa), from the interior to the exterior of wood. |

Se modelan esfuerzos de secado en una sección transversal de madera sólida, producidos por gradientes de humedad asociados a los fenómenos de contracción y sorción mecánica. En particular, se implementa CVFEM con elementos finitos triangulares, interpolación lineal de la variable independiente al interior de él y programado en lenguaje Fortran 90. El modelo se valida contrastando re-sultados con trabajos similares disponibles en la literatura especializada. Finalmente, se muestran resultados originales de la modelación aplicada al secado isotérmico (20 ºC) de madera sólida de álamo (Populus tremuloides): distribución bidimensional de esfuerzo/deformación y contenidos de humedad para tiempos de secado igual a 40, 80, 130, 190 y 260 (h) y evolución transitoria de esfuerzos normales (-2.5 and lt; σ͓ ͓ and lt;1.2, MPa), desde el centro a la superficie de la madera.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/20545Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 31, núm. 1 (2011); 171-183 Ingeniería e Investigación; Vol. 31, núm. 1 (2011); 171-183 2248-8723 0120-5609Salinas, Carlos and Chavez, Cristian and Gatica, Yerko and Ananias, Rubén (2011) Two-dimensional wood drying stress simulation using control-volume mixed finite element methods (cvfem).
