摘要
Over the years the finite strip method (FSM) has proved lobe an invaluable tool in the study of buckling modes in thin-walled structural members. This paper presents a formulation of the FSM, which is able to predict the buckling stresses of initially perfectly straight thin-walled inelastic members under uniform compression. Plasticity is accounted for by means of plastic flow equations. Previous shortcomings of plastic flow theory with respect to the modeling of buckling problems are overcome by deriving an expression for the inelastic shear stiffness from second order considerations.
