Abstract (EN): A numerical method for the calculation of the internal stress state that develops within structures subjected to mechanical and steady state or transient hygroscopic loading conditions, has been developed. The method encompasses a layer by layer approach whereby the structure is discretized into plies with different material properties corresponding to the different ply moisture contents. The proposed method has been validated against finite element solutions, and results from its application on a fully characterized epoxy polymer binder are presented. The impact of the moisture induced viscoelastic behaviour on the structural response of the case studied is discussed.
