| Abstract: | On the basis of standard linear viscoelastic model and Karchanov damage evolution assumption, the creep postbuckling of a compressed column with damage and initial imperfection is studied. Numerical results show that the effect of damage on the path of creep postbuckling of the compressed column is significant. |
