CADEMARTORI, Pedro Henrique Gonzalez de; MISSIO, André Luiz; GATTO, Darci Alberto  e  BELTRAME, Rafael. Prediction of the modulus of elasticity of Eucalyptus grandis through two nondestructive techniques. Floresta Ambient. [online]. 2014, vol.21, n.3, pp.369-375.  Epub 29-Jul-2014.

The present study aimed to estimate the modulus of elasticity (MOE) at static bending of Rose gum (Eucalyptus grandis) heartwood and sapwood through two nondestructive techniques: ultrasound and stress wave. Sixty samples of heartwood and sapwood were prepared. Nondestructive tests were performed using ultrasound and stress wave timer equipment, while destructive tests were carried out in a universal machine through static bending tests. The main results showed that the heartwood presented better behavior than the sapwood in the non-destructive tests. However, the best model was obtained considering both wood types through the ultrasonic technique. Therefore, stress wave and ultrasonic techniques could be employed to estimate the modulus of elasticity of Rose gum wood.

Palavras-chave : ultrasound; stress wave; wood technology.
