 note = {3D FE elastic program was included to my FE software package in 1989, though the theory and FE formulation of this 3D FE elastic program was not described. The functionals for 3D and 2D elasticity are explained in this paper regarding the variational principle that is more sophisticated theoretical basis of FE formulation than the principle of virtual work. The FE formulation of 3D elasiticity is explained here based on the principle of virtual work, because the 3D elastic program including my FE software package was developed using the principle of virtual work., 紀要論文},
