We also dedicate a section to discuss a model with the frictional damping term λut, is replaced by a viscoelastic damping term ∫t 0 g(t-s)Δu(s)ds.engExistence and uniqueness of solutionExponential decayFrictional dampingKirchhoff equationUniform stabilityViscoelastic dampingArtigo2-s2.0-84987703580
