In this report, the nonlinear finite element analysis of three-dimentional scissors structure composed of beam-like members with hinge points is described. We have already formulated the FEM of the 3D scissors structure by introducing 3D Green-Lagrange Strain, which does not cause strain with respect to the rotation of the rigid body, and using the virtual work principle. Also it is possible to correspond to shaft rotation by using the torsion angle of the member axis.The numerical calculations are carried out, and 3D scissors structure is analyzed. We will verify the results and show the usefulness of the analysis.
