| Abstract: | By using the method of limited unit , we build up the stiffness matrix of triangular unit of the light gauge sheet of variable thickness and produce the mathematic model for the computation of the stress and displacement at the center of the triangular unit.. Through the analysis of the static force of a missile wing and experimental comparison, we find out that the demand of the structural design accuracy can be met by using this model. |
