I am researching the drilling simulation of CFRP laminates. In Abaqus, I established four layers of plywood with Element Type C3D8R; There are 3 layers of zero thickness cohesive units between layers; The Element Type of the tool is C3D4. When drilling, it is easy to encounter the problem of excessive distortion of the unit as the drill bit penetrates. I did not use ALE, but instead turned on Hourglass Control and Distortion Control. I set Hourglass Control to combined, and the length ratio of Distortion Control to 0.1, 0.2, 0.25, and 0.3, but the problem remained unresolved. May I ask how to solve this problem?
