Effect Of Restricting Buckle Depth In Circular Cylindrical Shells Repeatedly Compressed To The Buckling Limit

The reduction in critical buckling load for a thin-walled cylindrical shell which occurs under repeated compression is a function of the depth to which the buckle is permitted to develop. It shows that a nickel cylinder whose R/t is of the order of 400 does not experience any load reduc tion on repeated load when the buckle depth never exceeds the thickness of the shell, and that buckle depths which are equal to or greater than 2.5t give the same results as are obtained in unrestricted buckling. It proves, too, that by using the method of buckle restriction it is possible to cause a cylindrical shell to buckle uniformly over its entire length. (Author).
