Dynamic Behavior of a Semi-Infinite Elastic Hardening- Softening Beam Subjected to a Pulse Loading

Abstract

The dynamic response of a semi-infinite elastic hardening-softening beam subjected to a suddenly applied moment and a transverse pulse loading at its tip, with the magnitude being inversely proportional to the square root of time, is analyzed. Four different deformation modes are identified. The numerical results demonstrate that in one of these modes, a finite softening region exists and propagates along the beam.
