Prediction of Maritime Pine Boards Modulus of Elasticity by Means of Sonic Testing on Green Timber

Timber buildings are experiencing a rapid diffusion due to their good performance and sustainability; however, some steps of structural timber production process, such as drying, energy-intensive environmentally impactful, many wood species also affected by low yield. Therefore, it would be important determine the quality green material, that is, in wet condition, before undergoing most impactful expensive steps. This paper describes research aimed at quantifying variation dynamic modulus elasticity MoEdyn, which is commonly used for mechanical grading, from dry condition Sardinian maritime pine boards laminated timber, examine relationship between MoEdyn. The MoEdyn was determined measurements velocity sonic waves propagating through boards. results show can estimated starting testing so providing basis implementing pre-grading order obtain reduction manufacturing costs, abatement environmental impact, increase grade
