Some remarks on the problem of column buckling

Abstract

It is shown that within the framework of an earlier analysis of the author the difference between the results of Engesser's procedure and of a modified Engesser procedure can be accounted for entirely by a difference in assumptions concerning the form of the assumed one-dimensional stress strain relations. Depending on a choice between two types of expressions for the description of axial normal strain and transverse shearing strain in the beam it is either Engesser's procedure or the modified procedure which requires the presence of certain nonlinear terms in the stress strain relations. © 1982 Springer-Verlag.
