摘要
本文发现在涉及经典板理论的著作中,给定两正交自由边交点B的自由角点的边界条件R_B=0是不正确的。联系Kirchhoff变换的正确运用,本文提出了一个正确的自由角点条件R_B=2(M_(xy))_B,并以同理给出一个新的广义简支边的边界条件。
The paper discovers the boundary condition of free corner R_B= 0 to be in correcte in some related to classical plate theory's books, which is the point B of intersection of two orthogonnal free edges, connecting with correctly use for the Kirchhoff-Transformation, the paper proposed a new boundary condition of free coner B: R_B = 2(Mxy)_B. As well as a new boundary condition of the generalized simply supported edge by the same reasons.
