Dear all,
As I am modeling shear banding phenomena in 3D, I am confused on what element type I should adopt, since there are many versions in literature. In 2D simulation, some author suggests using quadrilaterals consists of 4 cross-triangular elements, while some other use 9 node quadrilaterals. In 3D, some author use 20 noded hexahedral while some other use 8 node hexahedral with 1 integration point.
So in all I am very confused about this. And I wish there could be some paper recommanded to address the element-type issue in modeling shear banding. Could anyone please help me with this?
Thank you very much!
