NOTE: Text or symbols not renderable in plain ASCII are indicated by [?]. Abstract is included in .pdf document. In this report of work on the ultimate strength of thin sheet metal panels, the general formulas for the design of such panels has been developed. Two important equations have been obtained by theoretical reasoning, namely that the total load carried in compression by any unstiffened, simply supported panel can be given by P = C[?] and that the constant of C is given by C = f([?]) = f([?]) where E = the Young's modulus of the materials [?] = the stress at the supported edges; t = the thickness of the material; b = the width of the panel; R = the radius of curvature of the panel. This treatment has been extended to the case of stiffened panels, both flat and curved, and the predicted loads have been found to give a good check with the loads obtained by actual failure tests of such panels. Design curves are given to facilitate calculations and complete calculations of particular cases are carried out in the Appendices.
