摘要：

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 beta is stretched or compressed with constant speed. It is found that for beta>8/7 no dynamic snap-through will occur when the arch is stretched. However, as long as beta<4, dynamic snap-through is still possible when the arch. is compressed.
