ABSTRACT:
System and method of simulating large deformation and rotation of a structure in a finite element analysis used for improving structural design is disclosed. A solid finite element is configured for simulating large deformations and/or rotations of a structure. The solid finite element comprises only corner nodes with each node having six degrees-of-freedom (DOF), three translational and three rotational. In other words, each node is configured to include translational deformation and rotation deformation, each of the translational and rotational deformation has three components corresponding to one of the six DOFs. The solid finite element has a plurality of external edges. Each external edge has two ends, each end is located at one of the adjacent corner nodes. Additionally, translational deformation at mid-edge point of each external edge is implicitly embedded in the translational and rotational deformations of two adjacent corner nodes.
