文摘:以simple算法为基础，建立了圆柱坐标系下非轴对称三维湍流流动离散化的代数方程，从而可以对非轴对称三维湍流流动进行数值模拟 - Eigenequation about singularity , singular stress fields and electrical displacement fields near the interface edge are obtained under axisymmetric distortion . finally , a special finite element formulation which is based on the principle of minimum potential energy has been developed for determining the orders of the singularity of the singular stress fields around the singular point ( interface edge , interface corner and the interface crack ) in the bonded dissimilar anisotropic / anisotropic , piezoelectric / piezoelectric as well as piezoelectric / anisotropic materials . the numerical results show that this method is very convenient and efficient
最后，从最小势能原理出发，在仅仅考虑奇异性支配区域这一前提下，对于弹性接合材料的平面变形问题和拟平面应变问题，以奇异点为原点分别建立极坐标系和圆柱坐标系，通过分部积分消除厂项，从而使奇异性问题的求解由原来的二维降为一维；对于三维变形问题，以奇异点为原点建立球坐标系，通过分部积分消除项，从而使奇异性问题的求解由原来的三维降为二维。 - In the first part of the paper , the explicit form of difference equation and periodic boundary condition is derived in cartesian coordinate system . secondly , the dispersive characteristic is analyzed in cylinder coordinate system for many high power microwave devices use cylinder sws . and then the method is extended to calculate the band structure of 2 - d photonic crystal , a modified yee ’ s grid is introduced to calculate the dispersive characteristic in the case of triangular lattice , so that both square lattice and triangular lattice cases can be solved in cartesian coordinate system
