| 英文摘要 | In the present paper, a continuous-discontinuous cellular automaton method is developed to model the discontinuous problems caused by regular frictional contact, in which level set method, discontinuous enriched shape function, discontinuous cellular automaton method and contact friction theory are combined, by which an analysis from continuity to discontinuity can be achieved, and no assembled stiffness matrix but only cell stiffness is needed in the whole calculation, because of the use of discontinuous cellular automaton method. In the present method, level set method is used to track the discontinuous surface, and discontinuous enriched shape function is employed to describe the discontinuity of displacement and stress. Contact friction theory is applied to construct the Coulomb frictional contact model of discontinuous surfaces; besides, combined with discontinuous cellular automaton method, a new mixed iteration method is proposed to obtain the solution of the problem, and no assembled stiffness matrix is constructed. And the frictional contact iterations are done simultaneously with the updating of cellular automaton, in which the contact states and contact areas can be previously obtained in the cellular automaton updating process, and the efficiency can get much higher. Finally, some numerical examples are given to show that the present method is effective and accurate and can be further extended into some practical engineering. |
