ESDU Struct 02.01.10 provides a graph from which the buckling stress coefficient may be obtained for a slightly curved plate loaded along its axis with the edges clamped but subjected to negligible lateral restraint. The bucking stress coefficient relates the buckling stress to the modulus of elasticity multiplied by the square of the ratio of plate thickness to width. The plate is assumed long enough for the effect of the edge conditions at the loaded edges to be negligible. The curves relate to various levels of initial irregularity, defined as the maximum inward deviation of the surface from a straight edge placed anywhere on the outside of the plate in an axial plane. They were derived from the curves of ESDU Struct 02.01.11; for a zero radius of curvature those curves agree with theoretical results for flat plates, and for the greatest radius of curvature considered they also fit theoretical results closely in the range of practical interest. Curves for radii in between were interpolated.
