“…This stress ratio S r is higher than the one we can calculate from the study published by Widehammar [16] in the case of the compression of an oven dried clear spruce wood in the radial direction, that is, S Widehammar r ≈ 1.5 for a strain rate multiplied by 1.25 · 10 3 . However, our stress ratio is close to the one obtained by Eisenacher et al [17] in the case of the laterally confined compression of a 12% moisture content clear spruce wood in the direction perpendicular to the fibres S Eisenacher r ≈ 1.7 for a strain rate multiplied by 1.50 ·…”

“…This stress ratio S r is higher than the one we can calculate from the study published by Widehammar in the case of the compression of an oven dried clear spruce wood in the radial direction, that is,

S_{r}^{W i d e h a m m a r} \approx 1.5

for a strain rate multiplied by 1.25·10 3 . However, our stress ratio is close to the one obtained by Eisenacher et al in the case of the laterally confined compression of a 12 % moisture content clear spruce wood in the direction perpendicular to the fibres

S_{r}^{E i s e n a c h e r} \approx 1.7

for a strain rate multiplied by 1.50·10 3 . Eisenacher et al attribute this high stress ratio value to the lateral confinement which he applied on the direction perpendicular to the fibres, leading to zero lateral strain in the radial or transverse directions, depending on the initial orientation.…”

“…This study clearly showed the huge influence of the strain rate on the radial compression behaviour of spruce wood, which was less visible in the transverse direction due to the early failure of the specimen when loaded in this direction. In the same way, Eisennacher et al presented experimental results on crushing tests of spruce wood. They varied in orientation, loading rate, and lateral constraint of the specimen.…”

An extensive series of compression tests with birch plywood specimens is conducted in the out‐of‐plane direction. Various experimental conditions are tested with different temperatures and strain rates. To this end, a specially designed Split Hopkinson pressure bar protocol is defined, and the specimen dimensions are validated from quasi‐static EN789 standards experiments. Temperatures are ranging from ambient down to −170°C, while strain rates are increased from 0.004/s up to 700/s. The analysis of the experimental results focuses on the hardening behaviour and the following densification regime at large strains. Evolution with temperature and strain rate of the four coefficients of the stress versus strain curve interpolation is discussed, and models are proposed.
