Résumé
To clarify the contribution of mechanosorptive e ect and compliance evolution according to moisture content during adsorption under load creep tests on longitudinal spruce specimens in variable environment were performed. By comparing di erent loading history we observe that creep increase during the first adsorption (++ e ect) mostly results from the increase of compliance induced by higher moisture content. We also discuss the viscoelasticity and mechanosorptive interaction during creep.
