Strain assisted diffusion: Modeling and simulation of deformation-dependent diffusion in composite media

摘要

In this work, we develop a model for strongly-coupled, deformation-dependent diffusion in composite media at finite strains. The coupling incorporates the effects of deformation into the diffusivity tensor. A time-transient, three-dimensional variational formulation is developed and then discretized using the Finite Element Method in conjunction with an implicit staggering scheme to resolve the coupled mul-tiphysics. Numerical examples are provided to illustrate the model.
