Interaction between mechanosorptive and viscoelastic response of wood at high humidity level

Abstract

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