It is believed that energy can be saved by introducing fatigue-structural changes into wood using cyclic compression. Despite the common faith only one concept has been reported to save some 30% of energy [2] the reason for the saving still remaining unknown. Emphasis of the disquisition is on large i.e. inelastic compression and changes of wood cellular structure at the level of annual rings. We address the physics of our unexpected and unexplained results of unequal yield deformation.
