Instability of an elastically supported Timoshenko beam under a traveling inertia load

Abstract

The instability of an elastically supported infinite Timoshenko beam under constant velocity traveling inertia load has been investigated. The regions of dynamic instability are determined for different values of the elastic foundation constant. Since the occurrence of this dynamic instability reduces the axial buckling load of the beam, the result is important for the study of buckling of a continuous beam.
