Untersuchungen zur Bestimmung der Poissonschen Konstanten an Fichtenholz

Abstract

On spruce wood, the MOE in all three main directions (longitudinal, radial, tangential) and the six Poisson ratios were determined after climatisation at 20 °C and 65% rel. humidity using an incremental displacement transducer. The ratios of the different MOEs were calculated as ET:E R:EL =1:2.43:25.4. The following Poisson ratios were determined: μRL=0.022, μTL= 0.015, μLR=0.376, μLT=0.420, μTR= 0.335, μRT=0.640. © 2007 Springer-Verlag.
