Modelling of Pd-membranes deformation during hydrogen separation

Abstract Pd-membranes used for hydrogen separation work at elevated temperatures under pressure causing plastic deformation of the membranes. To complicate the problem these membranes are very thin. Thickness varies between 1 and 5m. Different modelling approaches can be used for modelling of this complex situation. Variety of 2D and 3D ABAQUS modes are tested for this purpose. To simulate interface between the membrane and substrate, some models include contact analysis. Results from different models are compared.
