THEORETICAL AND EXPERIMENTAL ANALYSES OF THERMAL BUCKLING PROBLEMS OF LINER SHELLS ——THEORETICAL PART 1)

The buckling problem of liner shells is a major problem in reactor containment's design Because of the unilateral constraint and complex boundary condition, it is difficult to investigate post-buckling behavior of liner shells In this paper, the local liner shells are considered as the liner plates with the special initial imperfection forms Three liner shell models: four-point-supported liner shell, clamped liner shell and five-point-supported liner shell are proposed and investigated, respectively...
