BUCKLING AND FAILURE STRENGTH OF PLATING PANELS LOADED IN SHEAR.
Abstract
Three series of tests to explore the shear buckling and failure characteristics of plating panels are reported herein. In the first series, unstiffened panels of three grades of steel and one of aluminum were tested in a balanced cantilever shear frame. Panel aspect ratio was 5 to 1 and width-to-thickness ratios varied from 30 to 160. The results of thes test indicated that the effective edge condition of the panels was between simple support and complete fixity even though massive clamps were used. The second series of tests involved aluminum panels .050 inches thick with single central stiffeners tested in the cantilever frame. The final series of tests was performed in a square test frame loaded on a diagonal. Each panel was divided into five bays of 5:1 aspect ratio by tee stiffeners. Subdivided width-to-thickness ratios varied from 57 to 162. Stiffeners and plates were fabricated from Cor-Ten steel. The results have permitted some general observations relative to the design of naval structures, the most important of which is the fact that the stress at inception of permanent buckling can be predicted with good accuracy, provided the yield stress of the material is known, even though only approximate elastic critical stress data for the configuration is available.
