摘要
依据能量原理建立降维变分法,该方法将物体离散为条,在一定约束下,一条独立求解能量极值,可有效简化数值计算,本文研究分条离散方法,极值约束,边界条件处理并给出证明。更重要的,该方法揭示了新的物体形变运动规律。在此也做了分析。
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.
