Buckling optimization of compressed bars undergoing corrosion

Mark M. Fridman , Isaac Elishakoff

Abstract

This study is devoted to the optimal design of compressed bars under axial compressive forces and exposed to a corrosive environment. The initial volume of the structure is taken as an optimality parameter. Gutman – Zainullin\'s exponential stress corrosion model is adopted for analysis. Analytical and numerical results are derived for optimal variation of the cross-sectional area of the bar along its axis.
