TL;DR: Synchrotron radiation phase-contrast X-ray tomographic microscopy was applied to observation and identification of the features of spruce anatomy at the cellular lengthscale and it is suggested that the position of sub-voxel-sized features can be determined indirectly using watershed segmentation.
Journal ArticleDOI
Determination of Young’s and shear moduli of common yew and Norway spruce by means of ultrasonic waves
TL;DR: In this paper, the ultrasound velocities of longitudinal and transversal waves applied to small cubic specimens and derived the elastic constants from the results were used to determine the Young's moduli of yew wood.
Journal ArticleDOI
Moisture-dependent orthotropic elasticity of beech wood
TL;DR: In this article, the elastic properties of beech wood were determined at different moisture conditions and the determined properties can be used to investigate the mechanical behaviour of wood structures including different moisture properties.
Journal ArticleDOI
Three-dimensional elastic behaviour of common yew and Norway spruce
TL;DR: In this paper, the authors performed tensile tests on dog-bone-shaped yew specimens and determined the three Young's moduli and six Poisson's ratios using a universal testing machine and a digital image correlation technique.
Journal ArticleDOI
Measurement of standard and off-axis elastic moduli and Poisson's ratios of spruce and yew wood in the transverse plane
TL;DR: In this paper, a tensor transformation was used to compare the experimental results with those calculated by tensor transformations to assess whether it is admissible to treat the investigated wood species as orthotropic materials.
