| Abstract: | The concrete material model, contact analysis, element birth and death, and the technology of constructing the finite element model are the most important factors to solve the problem of stress state of the penstock structure on the downstream dam surface with FEM.This article detailedly explains the application of the above four problems in ADINA8.2.In order to solve the difficult proplem of evaluating the earthquake-resistance safety of the system of post-cracking penstock-dam-foundation, a new research method is proposed. |
