| Abstract: | By adopting Lagrange's multipliers method for functional analysis of extreme value, the author makes an optimal stability analysis of a section of compression bar under the constraint of elastically hinged support at both ends. A common expression is obtained for expressing the rule of optimal distribution on the section and the function of flexure of the compression bar under the constraint of arbitrarily elastically hinged support. And an integrated formula is given for calculating critical load. |
