The present work was conducted to simulate mechanical behavior of 12% moisture content Ana tree and Red Oak wood material and their composite under load using Analysis of Structures Computer Program (ANSYS 11). Wood blocks with dimensions 1.2m×0.2m×0.2m were modeled in the program then defined and meshed. Each model was constrained at its two ends and a distributed load of 500 Kilo Pascal (KPa) was applied on its upper surface. The solution of linear problem was run and calculation control in addition to result processing was accomplished within the Post Processor (POST1). Deformed shapes, shear stresses and von-Mises stress were displayed. The results showed that wood of Ana tree demonstrated more deformed shape as compared with Red Oak species and the composite. The highest shear stress on XY plane was shown by the composite (21374 Pascal), whereas the lowest shear stress on this plane was recorded by Ana tree (1529 Pa). In case of shear stress in YZ plane, the Red Oak recorded 8692 Pa as the highest value, while composite showed 7785 Pa as the lowest value. The highest shear stress in XZ plane was demonstrated by Red Oak with value of 28834 Pa and the lowest shear stress in such plane was 22660 Pa recorded by the composite. As far as records of von-Mises stress are concerned, composite and Ana tree wood showed the highest and lowest values as 144468 Pa and 135914 Pa respectively.
