From visual grading and dynamic modulus of european beech (fagus sylvatica) logs to tensile strength of boards [Elektronski vir]Plos, Mitja, gradbeništvo, 1979- ...The aim of the present paper is to assess the non-destructive indicating properties of Slovenian beech (Fagus sylvatica) logs and correlate them with the mechanical properties of the final product, ... which is boards. Beech logs were visually graded according to the standard procedure and vibrational frequencies were measured. Logs were further on sawn into boards which were also non-destructively tested in wet and dry conditions. Finally, the boards were experimentally tested in tension. Special focus was directed towards visual parameters of the beech logs and their influence on the overall quality of the output material. The longitudinal natural frequencies of the logs were studied as potential indicating properties. The results showed that a majority of the visual log grading parameters do not result in good quality timber in terms of strength and stiffness properties, and only few are decisive for the final classification. The coefficient of determination of the static MOE vs. dynamic MOE of logs was r2=0.13, whereas vs. the MOE of wet boards was r2=0.49. Using a few visual characteristics in combination with dynamic measurements of logs and of wet boards could help to increase the yield of high quality beech wood.Source: Forests [Elektronski vir]. - ISSN 1999-4907 (Vol. 13, iss. 1, jan. 2022, [18] f.)Type of material - e-articlePublish date - 2022Language - englishCOBISS.SI-ID - 92687363
