Comments

  1. The corner grid points G1, G2, and G3 should be input in consecutive order at the bottom face of the cohesive element. The corner grid points G4, G5, and G6 should be defined on the top face with G4 opposite G1, G5 opposite G2, and so on.
    If existing, the edge grid points G7, G8, and G9 should be provided in consecutive order at the bottom face of the cohesive element. The edge grid points G10, G11, and G should be defined on the top face with G10 opposite G7, G11 opposite G8, and so on.

  2. The element coordinate system for the CIFPEN element is:


    Figure 2.

    Two intermediate vectors, v1 and v2, are defined. v1 starts from the middle point between G1 and G4 and points to the middle point between G2 and G5. v2 starts from the middle point between G1 and G4 and points to the middle point between G3 and G6. The z-axis of the element coordinate system is obtained by the cross product of v1 and v2. v1 is taken as the x-axis. Finally, the y-axis is obtained by the cross product of the z- and x- axes.

  3. The coheisve material coordinate system is the same as the element coordinate system by default and can be defined as a prescribed system through PCOHE entry.
