Abstract
The anisotropy feature of wood confers versatility for designing products and wood structures. The objective of this research was to determine the modulus of elasticity and strength by compression on the radial, tangential and longitudinal directions, for P. Michoacana, P. pringlei and P. douglasiana wood. Compression tests were performed on 39 specimens and wood moisture content and basic density were calculated. For each of the species studied, the results of an analysis of variance between radial, tangential and longitudinal directions of modulus of elasticity and strength by compression, suggest a significant difference between the mean values of the three variables grouped into elastic and strength parameters. These results confirm that the elastic and mechanical properties of wood vary according to the direction in which they are measured, verifying the anisotropy feature of the material.
