Résumé:
The aim of this work is to give a results related to locally coupled wave equations with non-
smooth localized viscoelastic damping of Kelvin-Voigt type and localized time delay
(studied by Mohammad Akil et al[1]). The research aims to study the existence and
uniqueness of solutions under appropriate assumptions using semigroup theory. Using a
general criterion of Arendt-Batty, we show the strong stability of our system in the absence
of the compactness of the resolvent.
