Abstract
A formulation for minimum weight optimization of composite laminated struts is given. The minimum weight strut satisfies failure criteria of local buckling, overall buckling and maximum strain or maximum stress. Seven types of strut shapes, six composite materials and aluminium alloy are considered. The formulation requires the evaluation of the buckling coefficient, K, for both ends and one side simply supported and one side free for composite laminated plates of high aspect ratio, and the method of evaluation is also given. A computer program OPTSTRUT for carrying out the optimization procedure is described. Examples of strut design are carried out using this program and compared with existing designs. It was found that these results compared well with those from past investigators.Keywords
