<br/><br/> <br/><br/>Abstract<br/><br/>This study aimed to evaluate the static bending strength (fM) and modulus of elasticity (MOE) to static bending<br/>values of Eucalyptus grandis samples produced in different dimensions. It intended to identify samples that<br/>present similar mechanical properties to those recommended by other technical standards and those obtained<br/>according to NBR 7190. The samples were made in agreement with the dimensions of the following standards:<br/>IPT, AFNOR B51-016, ASTM D143, CEN-EN 408, COPANT 555, and NBR 7190. The strength was significantly<br/>reduced with the increase of the sample dimensions. The MOE was significantly influenced by the samples size with<br/>the values showing a parabolic trend. The samples produced according to COPANT 555 (5 x 5 x 75 cm) presented<br/>resistance values similar to the values obtained following NBR 7190 specifications, whereas for the MOE, the samples<br/>proposed according to the IPT presented the closest values of Brazilian technical standards (NBR 7190).<br/><br/>Keywords: mechanical testing, modulus of elasticity, mechanical strength, Eucalyptus grandis.
