A general decay result of a coupled system of nonlinear wave equations

This work is concerned with a nonlinear system of two coupled viscoelastic equations. Under some restrictions on the coupled functions, we establish, for a wider class of relaxation functions, a generalized stability result for this system. This result improves many results in the literature, such as the ones in Messaoudi and Tatar (Appl Anal 87(3): 247–263, 2008) and Liu (Non-linear Anal 71, 2257–2267, 2009).
