Amplitude modulation theory and its application to two-mode buckling problems. (English) Zbl 0578.73044
Summary: This paper aims to review Koiter’s theory of amplitude modulation of the local mode and presents it in a form suitable for general application. Various features of this theory are compared with Koiter’s general theory of 1945. The amplitude modulation theory is applied to two-mode buckling of stringer stiffened cylindrical shells under axial compression. New mode interaction results are reported involving the simultaneous local and overall buckling in which the local mode is postbuckling unstable.
