Abstract : The shock spectrum due to the motion of the foundation or isolator mass of a two-degree-of-freedom vibratory system is studied. The system had a cubic hardening elastic nonlinearity in the foundation or isolator restoring force. The system was impulsively shocked, and analytical, experimental, and numerical methods were used to determine the resulting shock spectrum....
