Description

The experimental results on the buckling of thin cylindrical shells with a reinforced circular hole under axial compressive load are presented and discussed. The shell around a hole is reinforced by thickening the annular area. The variation of buckling load with the thickness or the radius of the reinforcing area is measured experimentally for both cases of central loading and eccentric loading.<BR>It is found that the reinforcement by thickening the wall thickness is more effective compared with by broading the reinforcing radius in order to recover the buckling value of monocoque cylindrical shell with a circular hole. The specimens of cylindrical shells and reinforcement materials used for these tests were made of Lumirror Polyester Sheet.
