Three-dimensional interaction surfaces are presented for the computation of elastic buckling stresses for an infinitely long flat plate subjected to combinations of bending, shear, and transverse compression in its plane - a loading approximating that occurring in a shear web. Surfaces are presented for two sets of edge conditions:both edges simply supported and lower edge simply supported, upper edge clamped. Present results are in good agreement with data for one-load and two load limiting cases previously published.
