STABILITY OF STRAIGHT BARS SUBJECTED TO REPEATED IMPULSIVE COMPRESSION.
Abstract
The problem of the parametric resonance of a straight bar subjected to a periodic impulsive axial compression is analyzed. With the aid of the Floquet theory the boundaries of the instability regions (unbounded transverse motions) are established. The general results are illustrated with several specific examples, including elastically supported and sandwich beams for various boundary conditions. The new results are qualitatively related to the cases of parametric resonance problems of corresponding beams studied previously. (Author)
