Breakdown for a Kirchhoff-type Beam with a Fractional Boundary Feedback.

Abstract  A Kirchhoff-type equation describing the transversal vibrations of a beam is considered. The beam is clamped to a rigid base at one part of its edge and free at the remaining part. On the free part, it is subject to a feedback involving fractional derivatives instead of the classical velocity of the deflection and angular velocity. In presence of an external nonlinear source we prove that solutions blow up at a finite time. [ABSTRACT FROM AUTHOR]
