According to the nonhomogeneous anisotropic elastic and complex function theory, accurate boundary conditions of crack in composite material plate were founded to settle its boundary condition problems by conformal mapping method. 摘要针对含裂纹的复合材料板，根据非均质各向异性弹性理论和复变函数理论，通过保角映射方法建立精确的边界条件，解决了裂纹的边界条件问题。
B--Are all the boundary conditions CORRECT? 所有边界条件是否正确?
Enforce essential boundary conditions using Lagrange multipliers. 用拉氏乘子加强本征边界条件。
Two boundary conditions are needed to solve the equation. 解此方程式需要两个边界条件。
