THE INITIAL POSTBUCKLING ANALYSES OF THE LINER SHELLS

Based on the Donned's nonliner theory of plates and shells, the initial postbuckling characteristics are investigated for the stud supported liner shells under thermal loads.Considering the liner shells as the liner plates with the cylindrical imperfection, asymptotic analysis of the initial postbuckling is performed An example is provided which shows the postbuckling stability of the liner shell and the validity of asymptotic predictions. The minimum postbuckling temperature of liner is also obtained.
