Restabilization in structures susceptible to localized buckling: an approximate method for the extended post-buckling regime

Localized buckling in structures has been extensively studied in the contex t of simple nonlinear models which capture the essence of the phenomenon ne ar the lowest critical load. In this study we apply a non-periodic Rayleigh -Ritz procedure to track localizations into the far post-buckling regime wh ere the structure regains stability after the initial destabilization. The results are compared against independent numerical solutions and good agree ment is found.
