1. Most probably there are something wrong in your program.
2. Only one type of B-bar exists, developed by Prof. Hughes, I think. But many types of EAS exists. That proposed by Simo, who maybe one of the greatest mechanical researcher in recent century, is quite good.
3. Try something simple to test. For example, forget Hyperelasticity at first and try to confirm if your finite strain calculated rightly. Let your EAS along and try to test B-bar element at first, which is easier to implement. |
