Wood Science and Technology Aims and scope Submit manuscript

Summary

Uniaxial compression creep tests of tubular spruce specimens loaded in uniaxial compression are reported. The relative humidity in the interior of the tube is varied in a controlled manner. The results indicate that creep is greatly increased in magnitude by simultaneous humidity changes of either sign.
