Título:Internal stability of a network of nonuniform timoshenko beam system
Abstract:In this talk, we will study the internal stability of a
non-uniform Timoshenko beam system on a network. For star-shaped
networks, we apply internal feedback on the rotation angle of all edges
except one. Under certain assumptions regarding the time-varying
physical coefficients, we prove the exponential stability of the system
if the wave speeds are equal, and polynomial stability otherwise. The
proof is based on the frequency domain method combined with the
multiplier approach. We conclude the presentation by generalizing the
results to general networks. I will present these results in
collaboration with Julie Valein from Université de Lorraine and Mohammad
Akil from Université Polytechnique Hauts-de-France.
Esperamos vocês!
