‘I have read with interest the paper by J. E. Gibson and was pleased to note that his computer solution checks the results obtained in an earlier study of mine. Dr. Gibson’s early pioneering work in the development of computer programmes for cylindrical shells and the publication of his books and papers have been a stimulus for
similar work being carried out in the United States.'
The critical stress for a lipped plate of given geometry is normally found by solving a transcendental equation by numerical methods. By assuming that the minimum value of the buckling coefficient occurs when there is no transmission of shear loading from the lip to the flange, a solution can be obtained by a considerably simplified analysis. This is shown to give close agreement to the exact solution for a particular case. The simplified analysis allows the torsional stiffness of the lip to be taken into account; it can be applied to all lip shapes, and to many forms of constraint on the other longitudinal edge of the plate.
Equations which express end bending moment and end shearing force for a heavy elastic bar in a generalized state of vibratory motion are obtained, in terms of end transverse displacements and end rotations. These equations may be used to facilitate the solution of problems of vibration in systems of rigidly connected bars. The example of a simple portal frame is considered.
