| Abstract: | On the basis of the energy principle,the Variational method of reducing dimensions is set up.A body is divided into strips and the extremum of energy in a strip can be independently solved under certain constraints,so the numerical calculation is simplified.Moreover the theory reveals some interesting physical properties in body deformation and movement which are studied in the paper. |
