    Abnormal distortion on shell element (S4R) under Abaqus explicit compression?

    Hi FEA way, Thank you very much for your reply! I have double checked the mesh quality and also geometry including overlapping faces. I guess the issue should most likely lie in the "All* with self" contact. Because the weird distortion happens at step 0 only where there is no small...

    Abnormal distortion on shell element (S4R) under Abaqus explicit compression?

    Hi everyone, I have a question that has been bothering me for a month. In Abaqus Explicit, I used shell (S4R) to simulate a compression experiment. I chose 'general contact' with 'all* with self' for the contact settings. However, there is a distortion as shown in the picture starting at the...
