| Abstract: |
| This paper studies the mechanical behavior of solid electrolyte under the coupled mechanical and chemical fields.The electrolyte model under the coupled mechanical-chemical fields is investigated at first,and the corresponding finite element variational forms are given.Then,the coupling effect of the crack tip stress fields and concentration distribution of oxygen vacancies on the GDC (Gadolinia Doped Ceria) are discussed in details.The results demonstrate that the stress field of crack tip has a significant effect on the distribution of oxygen vacancies. |
