Tension wood generates axial tensile stress and tangential compressive stress during its formation, but the mechanism causing this stress is not yet fully understood. A micro-mechanical model is used to test different hypothetic mechanism, based on the assumption that one of the constituents of tension wood undergoes a dimensional change during the formation of the wall. The consistency between the outputs of the model and known facts about tension wood behaviour is used to assess and discuss various hypothetic mechanisms.
