Document type: Technical Note
Abstract: The emphasis of this note is placed on finding out whether dynamic snap-through will occur when a shallow arch resting on an elastic foundation with elastic constant β is stretched or compressed with constant speed. It is found that for β>8/7 no dynamic snap-through will occur when the arch is stretched. However, as long as β<4, dynamic snap-through is still possible when the arch is compressed.
