The purpose of this study is to determine the mechanical property of the date palm stem (DPS) by analyzing the vibrations (BING test) along the samples. The BING vibratory system offers fast and reliable results for the estimation of elastic properties, especially the dynamic modulus of elasticity (MOED). Samples of 2 × 2 × 36 cm3 were taken based on the transverse distance along the stem to assess the results of this original research according to European standards. The classification of modulus of elasticity with respect to radial and tangential positions has made it possible to identify the most reliable parts for structural uses of the DPS. In addition, our results of the evolution of the MOED tested by the BING method have been determined in relation to frequencies and density. As a result, MOED is positively correlated with frequency in a significant way. Thus, a linear correlation was observed between the MOED and the density determined at 12% moisture content for DPS samples. Similarly, the MOED and density linearly correlate with the radial position of the samples. The results obtained concerning the relationship between its properties and the tangential position of DPS are insignificant. In addition, this study allows to put the appropriate choice according to the location of the sample adapted to the realization of a structure with the desired performance. [ABSTRACT FROM AUTHOR] |
