摘要
提出了三维 DDA的角 -面接触模型 ,并用矢量方法和罚函数法给出了详细的理论推导。算例表明 ,所提出的角 -面接触模型是正确的 ,并且易于编程实现。
The angle face contact model of three dimensional discontinuous deformation analysis is established and its formulation is det derived by vector analytical and penalty function method. The result of three typical examples indicates that the proposed model is correct and easy to program.
