Abstract: In this note we show that for a pinned half-sine arch under end couples snap-through buckling will occur unsymmetrically if the initial height of the shallow arch is greater than 6.5466r, ...

Abstract: In this paper we study the dynamic behavior of a shallow arch under a point load Q traveling at a constant speed. Emphasis is placed on finding whether snap-through buckling will occur. In ...

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 ...
