特征方程
Examples
- The eigenequations were applied to a cable filled with one kind of medium , and a special eigenequation was derived
将其用于只有1种各向同性介质填充情况，得到此种特殊情形下的特征方程。 - When the radius of the interior conductor equals zero , the circular coaxial cable becomes a circular waveguide , and its eigenequation was derived as well
在内导体半径等于零的情形下，同轴线即变成具有径向导体板的圆波导，得到圆波导的特征方程。 - 2 . eigenequation about singularity , singular stress fields and electrical displacement fields near the axisymmetric interface edge of two bonded dissimilar transversely isotropic materials are obtained under axisymmetric distortion . 3
然后，考虑电学物理量的影响，将上述特殊有限元法应用于压电/压电以及压电/弹性接合材料界面端奇异性的求解。 - 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。
