It is shown that the creep buckling of slender or thin-walled structures whose material deforms elastically as well as in consequence of time-hardening creep can be analyzed first as if the deformations were due entirely to steady creep. The results of this analysis can be easily modified to account for time-hardening creep and this modification does not involve any approximation when the time-hardening creep strain rate is expressed as the product of a function of stress by a function of time. The effect of simultaneous linearly elastic deformations can be taken into account by multiplying the critical time obtained for steady creep by a numerical factor. This correction involves no farther-reaching approximations than the usual steady-creep buckling analysis itself. |
