拟平面 meaning in English

quasi-plane

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。
