中文摘要：
将三维流形单元的位移函数从一阶拓展为二阶,基于最小势能原理建立了有限单元覆盖的高阶流形方法分析格式,详细推导了三维流形单元的刚度矩阵、等效节点荷载列阵以及位移约束矩阵.计算结果表明,提高物理覆盖函数的阶次可有效提高流形方法的计算精度.
英文摘要：
The three-dimensional numerical manifold with high-order displacement functions has been developed based on the tetrahedron element meshes. The global equilibrium equations of high-order manifold method are established by minimizing the total potential energy. The stiffness matrix, the loading matrix and displacement resistance matrix are derived and added to the global equations. The example of the cantilever bending under the area loading is calculated by the high-order manifold method and the numerical results agree well with theoretical solutions.
