5 Summarization Sheet is different from thick board。Generally,if the ratio of the thickness of the board and the minimal dimension of the board face satisfies: 8 1 ~ 5 1 100 1 ~ 80 1 ＜ ＜ b t We call the board sheet. Choose the ordinate origin as a point of the middle plane, and axes of x and y in the middle plane, z perpendicular to it, which are shown in fig. . x y z o We call the plane halves the thickness of the board middle plane
