چکیده
A semi analytical procedure based on the bubble finite strip method for the elastic buckling problems of thin-walled structures with variable cross section thickness is presented. The method is programmed to investigate instability phenomena of plate assemblies with tapered-thickness cross sections. Numerical studies are included, including tapered plates in compression and shear, L-sections and channels with variable thickness under bending, compression and shear, and a tapered thickness stiffened plate under compression. The results computed by this method show the accuracy and efficiency of the method for the instability phenomena of thin-walled structures with variable thickness.
