 各向异性问题
 anisotropic problem
 This paper translates the problem of plate with variable thickness into the equivalent two-dimensional anisotropic problem. For the case of linear varying plate thickness, we use the complex function method to get the stresses and displacements in the field. Then we use the variational principle to obtain the stress intensity factor of cracked plate with variable thickness. 本文将变厚度钣问题化为等效二维各向异性问题,对于厚度作直线变化的情况,利用复变函数方法得到域内的应力场和位移场,最后用变分原理求解变厚度含裂纹钣的应力强度因子。 短句来源 More interests are aroused in the anisotropic problem and heterogeneous problem. 各向异性问题和非均匀问题日益引起关注。 短句来源

 anisotropic problem
 In regions away from the central core of the stem, a simple closed form solution of the general anisotropic problem is given. We introduced an algorithm based on the Monte Carlo approach to solve the anisotropic problem. For the case of an internally pressurized tube, the anisotropic problem does not give rise to such radical differences in stress behavior from the isotropic problem. The stress field near the main crack tip is taken as a sum of a singular term of an anisotropic problem with stress intensity factor K, and a regular term. This matching function measures how well the anisotropic finite element mesh corresponds to the anisotropic problem. 更多

 In this study, one of the important points in the finite difference formulation for 3D anisotropic problems is the generalized approach for various boundary conditions. One of the important points in the finite difference formulation for 3D anisotropic problems is the generalized approach for various boundary conditions. In this paper the robustness with respect to anisotropic problems is considered. Many numerical experiments including unsymmetric and anisotropic problems, problems with jumping coefficients as well as realistic problems are presented.

 As Debye chiracteristic temperature denotes the average vibration energy of atoms or ions in a costal, while different atoms in the crystal may have different vibration modes, or the same atom in a noncubie crystal may have different vibration modes along different directions, there arises the problem of inhomogeneity and anisotropy of characteristic temperatures. 由于德拜特征温度标识着原子或离子在晶体内的平均振动能量,而不同原子在晶体内的振动模式,或同一原子在非立方晶体内的振动模式显然不同,这就发生了特征温度的非均匀性及各向异性问题。 本文提出了从粉末X射线衍射强度测定晶体特征温度的非均匀性及各向异性的方法。测定了CaF_2的特征温度。结果发现:Ca~(2+)离子在CaF_2晶体内的特征温度为400K,而F~-离子的特征温度为476K,二者相差76K。 M—and W—type haxagonal ferrites of Ce_xBa_(1-x) Fe_(12)O_(19)=Ce_xM, Ce_x Ba_(1-x)Fe_(18)O_(27) =Ce_xW and La_xBa_(1-x)Fe_(18)O_(27)=La_xW were prepared by oxalates coprecipitation method and sintering in the air.
