Influence of temperature on the embedding strength

In order to determine the influence of the temperature on the embedding strength at the yield threshold, 150 tests were carried out using 8 mm dowels. The tests were performed on samples of Pinus sylvestris L. with density in the range between 489 kg/m3 and 679 kg/m3 with an initial moisture content of about 11%. The tests were carried out in the longitudinal and transversal directions to the wood grains, with the temperature varying from 20°C to 240°C. The tests and the specimen dimensions follow the standard NF-EN 383.ZusammenfassungZum Bestimmen der Lochleibungsfestigkeit bei zulässiger Verformung wurden 150 Prüfungen mit 8-mm Dübeln vorgenommen. Die Kiefernproben (P. sylvestris) mit Dichten zwischen 489 kg/m3 und 679 kg/m3 hatten eine Ausgangsfeuchte von rund 11%. Die Prüfungen wurden parallel und senkrecht zur Faser durchgeführt. Die Temperatur variierte zwischen°C 20 und 240°C. Tests und Probenabmessungen entsprachen dem Standard NF-EN 383.
