In thin-walled bars with open cross-section, built from flat walls, cases are found in which, the cantilever wall, elastically restrained in the web, is compressed, and at the same time, longitudinal variation in stresses along its length occurs. Such a wall can be analyzed as a cantilever thin plate, elastically restrained against rotation on the longitudinal supported edge. The paper presents the results of investigations into the stability of elastically restrained cantilever plates for varied stress intensity in the longitudinal direction. Graphs of plate buckling coefficients (k) were determined and approximation formulas were derived for technically crucial stress distributions and different degrees of the plate edge elastic restraint. The impact of longitudinal stress variation and of the degree of elastic restraint on the plate buckling modes was analyzed. (C) 2015 Elsevier Ltd. All rights reserved.
