Investigation of oscillating climates for wood drying using the flying wood test and loaded beams: need for a new mechano-sorptive model

In this work, the effects of moisture content variations produced by oscillating drying conditions have been studied by means of non-symmetrical drying (flying wood) and loaded drying (3-point bending test). The oscillating conditions are intended to produce a mechano-sorptive creep that is able to...
