讲座内容：

In this talk, I will talk about the multiphysics finite element methods for some poroelasticity models. To reveal the multi-physical processes and to be helpful to propose stable numerical methods, I will introduce the multiphysics approach, which reformulates the original model into a fluid coupled problem. Then, a fully discrete finite element method based on the multiphysics reformulation is proposed to overcome locking phenomenon for displacement and pressure.  The stability analysis of the above proposed method and the optimal convergence order estimate are given, and some numerical examples are shown to verify the theoretical results.
