The present study is concerned with the analysis of the transient response of softcore sandwich structures in the postbuckling range using a higher-order geometrically nonlinear shell model including the transverse core compressibility. The transverse compressibility results in the development of a chaotic vibration with unpredictable wrinkling amplitudes and has significant effects on the eigenfrequency.
