摘要: Wood toughness is a mechanical property of interest in structural design where load impact must be considered, as the construction silos, bridges and formwork for reinforced concrete structures. However, not an integral part properties commonly investigated characterization this material. This study aimed to investigate, with aid analysis variance Charpy pendulum test, influence moisture content (30; 20; 12; 6; 0%) obtain angelim saia (Vatairea sp), Eucalyptus grandis, Pinus elliottii Corimbia citriodora wood species, considering orientation growth rings relation direction load. Statistical carried out using ANOVA Tukey test revealed significant on only respect wood. also showed equivalent results other three that is, did significantly toughness. Thus, we conclude may obtaining according species analyzed higher can provide values
