| Abstract: | In light of the defects of existing interface elements, a new calculation method for interface elements is put forward. The problems of considerable large error in stress calculation and large element overlapping in existing Goodman interface element can be avoided. The implementation steps of the model are given to facilitate the numerical calculation, and the method is proved to be reasonable and effective by the numerical model verification. |
