Hygro-locks modelling of the mechano-sorptive behavior based on integral formulation or internal variables

Abstract

session 'Computational Material Modeling of Wood and Wood Products'Wood is a porous, hygroscopic, anisotropic and non homogeneous biopolymer. It is classified as a viscoelastic material with mechanical properties depending on temperature and moisture content. The effect of creep is an important factor for the design and the durability of timber structures. Creep evolution results from the interaction between mechanical stress and moisture content variations
