Quantified energy decay of Euler–Bernoulli beams on an unbounded star-shaped network
Abstract
This work duscusses the energy decay rates of an infinite star-shaped network of beams with a slight degree of structural damping. Using frequency domain method we prove that the whole system is polynomially stable under some condition on the lengths of the rods.Downloads
