| Abstract: | By the application of the space finite-element computer program, the new laws of stress distribution on the section at the fixed end for cantilever plate and beam with linearly varying depth are revealed in this paper. On the basis of these results, the modified coeffecient formula of effective distribution width for plate and calculational formula of the stresses on the section at fixed end for beam are proposed respectively.These methods are very simple and have referential significance to designer. |
| Keywords: | cantilever plate with linearly varying depth effective distribution width section at fixed end modified coeffecient radial stress |
