Greetings to all !!
I want to simulate bending deformation caused in a thin 2 layered film, each layer having different vapor absorption coefficient due to uneven absorption it undergoes bending. (Same as bimetallic strip).
I have tried this simulation with temperature-displacement analogy.But want to perform using vapor diffusion in Abaqus.
I have performed 1st step of "mass diffusion" in Abaqus, but don't know how to use this concentration gradient data to get deformation.

Also, how should I plot deformation curvature graph with respect to time in Abaqus.
I have attached image of what I am trying to simulate.
(I am new to Abaqus and this is my first project, please guide me. )

Check the documentation chapter "Predefined fields for sequential coupling". The input file template provided there is for a sequentially coupled moisture-stress analysis involving a predefined field of normalized concentrations used in a stress analysis.
