DAVALOS-SOTELO, R.; PAZ PEREZ-OLVERA, C. de la  y  BARCENAS PAZOS, G. M.. Impact resistance values for ten mexican oak woods (Quercus). Rev. Chapingo ser. cienc. for. ambient [online]. 2010, vol.16, n.2, pp.215-226. ISSN 2007-4018.  https://doi.org/10.5154/r.rchscfa.2009.10.039.

Impact resistance or toughness values are presented for ten oak wood species from four Mexican states (Jalisco, Mexico, Puebla and Veracruz) tested in green condition with a FPL machine. No significant differences were detected in the toughness values among individuals of the same species growing in different regions of the country; therefore, a common value can be established for those species. There is a directly proportional effect of specific gravity on toughness, which is enhanced by including the thickness values of the cell wall as an additional independent variable in multiple regression analysis. Finally, values of the anatomical, physical and mechanical characteristics of Quercus crassipes wood are presented.

Palabras llave : Specific gravity; Mexico; Quercus crassipes; toughness.
