Radial compression behaviour of spruce wood was here studied in a steam environment at high strain rate and elevated temperatures. The difference in compression characteristics between earlywood and latewood was the main focus of the study. Effects of mechanical and chemical pre-treatments were also investigated. Mechanical pre-treatment affected the E- modulus of the samples more than the chemical pre- treatments. Also elevated temperature softened the wood. No significant compression of latewood could be registered with the methods tested.
