Triangular Shell Element for Large Rotations Analysis Academic Article uri icon

abstract

  • A method for the derivation of the geometric stiffness matrix of shells for large rotations analysis was presented. The approach is based on gradient methods that are equivalent to perturbation methods. The geometric stiffness matrix is composed of four individual matrices, two in-plane and two out-of-plane matrices. The advantage of the approach is that it is independent of large strain formulations.
