摘要
将由三个物理覆盖构成的流形单元的数值流形方法推广至四个物理覆盖的情形，给出具体的数值实现过程，并将其应用于裂纹扩展的模拟，数值结果令人满意。
An extension consisting of improving the manifold element from three physical covers to four is given. The framework of numerical implementation is presented within the extension. The method is used to simulate crack propagation in rock specimen and the results are satisfactory.
