摘要

Due to the facts that the spatial moment force is non-conservative and the three components of the finite rotation pseudo vector are not independent, the ordinary variational principle, based on a functional achieving its stationary value, is not suitable for the problem subject to non-conservative loading. The finite element method proposed in this paper is based on the virtual work principle, rigid normal assumption, polar decomposition and total Lagrangian formulation.
