Theoretical and experimental studies of convoluted type structures are described. An incremental method for predicting the nonlinear large-deformation behavior of two-dimensional convoluted strips is shown. The method is applicable for elastic as well as plastic stress strain behavior of the material. The results of the two-dimensional analysis are extended to an analysis of a circumferentially-convoluted cylinder which deforms into a conical shape. Tests on typical two- and three-dimensional convoluted metal specimens are described and correlations of theoretical predictions with experimental results are shown.
