Creep Buckling of Slender Columns

A methodology is introduced for calculating the allowable buckling stress in equipment operating in the time-dependent (creep) range. Norton’s equation coupled with various procedures such as the stationary stress method, classical creep buckling equations, and the isochronous stress-strain diagrams are utilized to obtain a practical design approach for equipment operating in the time-dependent range. Various components are investigated such as slender columns, cylindrical shells, spherical components, and conical transition sections.

Elastic And Plastic Deformations

SummaryThis paper is concerned with the solution of the creep buckling of columns. Instantaneous elastic and plastic deformations, as well as the transient and secondary creep, are considered. Formulae for the critical time at which a column fails are presented for integral values of the exponents appearing in the creep law.
