PARTICLE IMAGE VELOCIMETRY FOR OBTAINING THE YOUNG’S MODULUS IN WOODS

Abstract

Proposing technological innovations in the investigation of the structure and behaviour of wood is important to optimize its use. The assimilation of methods diffused in other areas, such as particle velocimetry (PIV), can allow a rich range of information for different aspects. It was aimed determine of the Young module, applying the PIV technique and that is independent of the density of the wood. The Young modulus value was obtained by destructive test, by the technique of transverse vibration and also by the PIV technique. Was used Cedrela spp. and Eucalyptus cloeziana and the data from the Young module were compared and correlated. The PIV technique presented values of the Young's modulus similar to those of the universal test machine. The PIV technique proved to be an accurate and simple execution tool for the calculation of the young module of wood by means of image analysis with the algorithm.
