The tubing column subjected to weight and reaction forces of constraint applied by the packer and the wall of a well is usually in a multiwave buckling state. This paper evaluates the maximum bending moment of the tubing. The evaluated value is twe times as large as that obtained on the basis of the helical buckling model (Ref. 1). This paper presents the formula used to calculate the allowable packing force. It can be simply used in the design of the tubing selled with a packer.

Based on the von Kārmān's plate theory,this paper is to deal with the freevibration,buckling and post-buckling of circular plates under inplane uniform pressureat the outer edges.The pre-buckling and the post-buckling static solutions are solved bytheir exact solutions.After that,the small free vibrations in the vicinity of the stablestatic equilibrium configuration are studied by the method of series in expansion to ex-actly obtain the eigenvalue and eigenfunctions of the dynamic eigenvalue problems.When the natural frequency of the loaded circular plate is equal to zero,we can get thecritical load of buckling and the corresponding buckling model.The critical loads ob-tained by this method are the same as those by the Bessel function.
